Learn from Last Season:Bad CollaborationNarrator:We are about to watch one of last season’sbuilding activities. Here students attempt todip a paintbrush in a cup of red paint and thenpaint a red X on a piece of paper without anyperson touching the paintbrush directly. Thecontestants have just begun Sam:OK, OK, OK, I have such a good idea. We’regonna get everyone to stand in a line and I’mgonna tie a string around my wrist and attachthe paintbrush to the string and then we’regonna tie everyone’s wrists together, and—Laura:Wait, I don’t understand how that’s gonna—Sam:And then everyone will stand close together andthere will be, like, a countdown and when we allswing our arms we’ll launch the paintbrush intothe paint—Tyler:Oh, I have an idea! Let’s just all make a pyramidwith the paintbrush at the top—Maria:You guys are being stupid.Eureka! Files Transcript3
Laura:I didn’t even say anything!Maria:This is stupid. I say we forget the paintbrush andjust put the paint in our mouths and then spit itonto the paper—Alex:Oh! That reminds me of this really funny thingthat happened at lunch yesterday! I was openingmy milk, and I squeezed the box as I was opening it and there was this spurt of milk in my eye,but it was really funny. What’s for lunch today?Laura:I think it might be pizza day. Because it’s Tuesday.Maria:No, no, pizza is Friday. Tuesday is tacos.Sam:We’re gonna tie our wrists together!Tyler:I don’t think putting paint in our mouths is a goodidea. Did anyone hear me about the pyramid?Maria:I’m putting the paint in my mouth right now.Ew—gross, it tastes foul.Narrator:Maria starts to cough and can’t stop coughing.Host:What’s going on over here?Narrator:The host listens in [his/her] earpiece.4Transcript Eureka! Files
Host:OK, I’m being told the producers are sayingthat you cannot ingest the paint. That was not agood idea. It’s toxic. It’s poisonous.Narrator:Everyone looks at Maria. She is turning blue.Host:We have to get her to the doctor, right now.Laura:Does that mean we lose?Eureka! Files Transcript5

Thomas EdisonGrouchy inventor Thomas Edisonreturns to anchor the panel of judgeson Eureka! Student InventorProducers are relieved to have Thomas Edison back on thejudging panel this season on Eureka! Without a big name likehis, they were concerned that even fewer people would tune in.For everyone’s sake, the producers hope that this season’s contestants pay Edison the respect he feels he deserves.After all, many claim that Thomas Alva Edison is the mostsuccessful American inventor of all time. He patented overa thousand inventions in the United States. He had humblebeginnings, however. Born on February 11, 1847, in Milan,Ohio, he was the last of seven children. His family was poor. Hiseducation consisted mainly of being homeschooled and readinghis father’s books. He got his first job when he was twelve yearsold, selling newspapers on the Grand Trunk Railroad. In histime off, he read in the public library. He conducted chemistryexperiments in the baggage cars. One of his experiments set thetrain on fire, but Edison wasn’t deterred. Even then, he knewthat you often have to figure out the wrong way to do something before you can find the right way.Eureka! Files Inventor7
One day he rescued a child from the path of a movingtrain. The boy’s father, who was trained to operate a telegraph,offered him lessons in telegraphy. He soon became a telegraphoperator. Before long he was inventing remarkable improvements to the telegraph that got the attention of financiers.With their support, he opened a laboratory in Menlo Park,New Jersey.His lab was the first of its kind. It was a busy place whereexperts collaborated, working on multiple inventions at thesame time. Research and marketing happened under oneroof. In this idea-rich environment, Edison invented thephonograph—the first device for recording sound! He alsocreated the incandescent lightbulb, his most famous invention.By the time he died, in 1931, Edison had patented anastounding 1,093 inventions in the United States. He patentedmore abroad. These include the Kinetoscope (which launchedthe movie industry), the microphone, the rechargeable battery,and a cement manufacturing process. Edison believes this listcements his place in history.8Inventor Eureka! Files

Jacques CousteauLover of croissants and aquatic life,seafaring Frenchman Jacques Cousteaureturns to Eureka!’s judging panelProducers are frustrated that Jacques Cousteau has returnedthis season as a judge on Eureka!, despite the fact that he wasnot invited back after the mess he caused last season. Jacques,however, is thrilled to be on the panel. He claims that this willbe Eureka!’s most exciting season ever!Jacques Cousteau likes excitement. Born on June 11, 1910,in the small town of Saint-André-de-Cubzac, France, Cousteauwas a curious child. Although not a good student, he was alwaysbuilding things and taking things apart to see how they worked.At age twenty-six he was in a terrible car accident that requiredmonths of rehabilitation. Armed with a pair of goggles, hebegan swimming daily in the sea. He quickly realized that hewanted to be able to explore the ocean. To do so he would needbetter equipment for breathing under water. So he decided totry inventing it.10Inventor Eureka! Files
Eureka! Files Inventor11
Cousteau and his inventing partner developed the AquaLung, which allowed people to stay under water while breathingfrom air cylinders (small tanks that can hold hours’ worth ofair). This advance opened human eyes to aquatic life in a newway. It also allowed for undersea rescues and recoveries thatwould have been impossible before.Cousteau also helped invent a deepwater camera. (As anavid undersea explorer he wanted to share with the world whathe experienced in person.) He increased interest in underwaterarcheology by spearheading the exploration of a famousRoman shipwreck. He went on to lead many more explorations,to write books, and to make films about his voyages and aboutocean life. His television series, The Undersea World of JacquesCousteau, was so popular it ran for eight years (a distant hopefor Eureka!).Jacques died at the age of eighty-seven in Paris, on land. Buthe was most himself when he was at sea. He once said, “Frombirth, man carries the weight of gravity on his shoulders. He isbolted to earth. But man has only to sink beneath the surfaceand he is free.”12Inventor Eureka! Files

GeorgeWashington CarverPeanut expert George Washington Carverjoins Eureka! as judge, brings love of plants,general human kindness to programProducers are pleased to announce that well-known inventor, professor, and all-around good guy George WashingtonCarver has joined the cast of Eureka!. Carver brings to thejudging panel a love of research and a deep knowledge of plantlife and agricultural inventions. He also brings a friendly andoptimistic perspective.The story of George Washington Carver could also be thestory of the peanut. And the sweet potato. Carver arguablyspent more time, care, and love on these two crops than anyperson before or since. He found over 400 new uses for them.The road to botany greatness wasn’t easy. Carver was borninto slavery in Diamond, Missouri, around January 1864. (Hewasn’t sure of his exact birth date.) He could not enroll at thefirst college that admitted him, because of his race. When hedid start college in 1890, he studied art (and music) becausehis school, Simpson College in Iowa, did not have a scienceprogram. But his instructor was impressed by his pictures ofEureka! Files Inventor15
plants, and pointed Carver toward Iowa State AgriculturalCollege’s botany program, where he was the first black student.This is where his career took root. He was a talentedbotanist and was hired to lead the prestigious TuskegeeInstitute’s agricultural department. While there, Carver set outto help struggling farmers and sharecroppers in the South.He worked hard to get the latest information about farmingmethods to them—even in remote locations —to help themremain self-sufficient. Until this time farmers in the South hadproduced mostly cotton. Carver helped to introduce many morecash crops. Cash crops are crops that can be sold for money. Healso told farmers to grow crops that break down the soil, suchas cotton, one year, and then the next year to grow crops thatimprove the quality of the soil, such as peanuts, sweet potatoes,peas, and soybeans. This method is called crop rotation. It keepsthe soil rich and fertile.Carver became an inventor when he tried to find new usesfor some of these new crops. He developed countless paints,dyes, and plastics made from peanuts, sweet potatoes, pecans,and soybeans. And, of course, he is often credited with inventing peanut butter! When asked why he didn’t try to make aprofit from his inventions, he said, “God gave them to me. Howcan I sell them to someone else?”16Inventor Eureka! Files

Hedy LamarrBrainy beauty Hedy Lamarr reluctantly agreesto judge Season 2 of Eureka!, citing boredomand a salary that will help pay for her guiltypleasure: strudelProducers are reportedly “OK with” Hedy Lamarrrejoining Eureka! as a judge. For her part, Ms. Lamarr claims“indifference” about returning to the panel. Her hopes for thestudent contestants include that they don’t give her a head cold,or lice.She was born on November 9, 1914, as Hedwig Eva MariaKiesler, to Jewish parents in Vienna, Austria. She changed hername to Hedy Lamarr in the early 1940s and became a moviestar known for her stunning looks. But there was more to HedyLamarr than starring roles in popular Hollywood films, greatbeauty, and six marriages. She was also an avid inventor.Her inventing began because she needed to entertain herself.She disliked Hollywood parties, so she had free time. She hada room in her house just for inventing. Some of the things shedeveloped there were everyday items (a better traffic signal, animproved Kleenex box—neither of which succeeded). But some18Inventor Eureka! Files
Eureka! Files Inventor19
of her other inventions were advanced technologies. She is bestknown for coming up with frequency hopping, changing thefrequencies of the radio signals that steer torpedoes. This meantthat an enemy would not be able to block them. She and herinventing partner, a composer named George Antheil, stumbledon the idea when discussing a piece of music he’d composedthat made use of synchronized player pianos. The two hopedto help America in World War II with their idea. The patent wasacquired by the US Navy, but the navy never found a way to useit. It took twenty more years for the idea to be put to use. Thiswas a major disappointment to Lamarr. Today a more advancedversion of frequency hopping is used in wireless phones, GPS—anything that makes use of Wi-Fi.Lamarr never profited from her idea and she was rarelyappreciated for her brilliant mind. This oversight irked her tono end and certainly contributes to her sometimes, shall we say,“quick-tempered” responses on Eureka!.20Inventor Eureka! Files

Ruth WakefieldGood day, children. I am Ruth Graves Wakefield, and Iam so very pleased to have the opportunity to clear up somedisappointing untruths that people have written over the yearsabout me and the invention of the chocolate chip cookie.I was born June 17, 1903, in East Walpole, Massachusetts.Articles about me almost always get that right, at least. Butthen the stories people tell! Here are some of the false storiesthat exist about me on the Internet. Some have claimed that theinvention of America’s favorite cookie was an accident. They sayI ran out of nuts and, in a panic, chopped up a Hershey bar tothrow into the cookie dough. It’s utter nonsense! I kept a strictinventory of my food pantries’ contents. I would certainly havenoted an absence of pecans, cashews, or our own ProfessorCarver’s peanuts prior to the dinner rush. I have also read thatI mistakenly spilled chocolate chunks into cookie dough afterbeing startled by a malfunctioning mixer. Having spent most ofmy life in kitchens—including my college years, during which Istudied the household arts—I assure you that my response to abroken appliance would have been mild irritation followed by acall to the repairman.Here is the truth about my cookie. It may not be the mostthrilling story in the world, but I can’t concern myself with that.Eureka! Files Inventor23
In 1930 my husband Kenneth and I opened a restaurant nearBoston called the Toll House Inn. The Inn was my pride andjoy, and I took its operation very seriously. Some have suggestedI was a bit of a tyrant with the staff. I don’t deny it. If a waitresswasn’t able to fold a napkin exactly right, I would suggest thatperhaps her skills were better suited to one of those “greasyspoons.” Yes, I wanted my restaurant to be the best. I’m fairlycertain that’s no crime. I was always trying to come up withnew dishes and desserts to attract more business. So I set out,quite deliberately, to invent a new cookie. And, after some trialand error with different ingredients, I created the chocolatechip cookie in 1938. I did it by improving a butterscotch cookiealready on the menu. That’s all there is to it.And while I know quite well that my cookie did not changethe course of history, I’ll leave you with this question. If you werestranded on a desert island, which would you prefer to have withyou—a box of lightbulbs or a box of chocolate chip cookies?24Inventor Eureka! Files

The LightbulbBEFORE THE LIGHTBULB: Life in the DarkFor most of human history, people got up at sunrise anddidn’t do much after sunset. There wasn’t much light in homesand traveling in the dark was dangerous. People could easily getlost or fall and hurt themselves.Of course people lit their homes before the lightbulb, butthere were lots of drawbacks to these early sources of light.Candles, for example, didn’t give off much light. Wood firestook a lot of effort to build and gave off unwanted heat whenthe weather was warm. Some species of whales almost becameextinct because the oil in their blubber was used as fuel for oillamps. Accidental fires were a problem with all of these lightsources and with the gas lamps that became popular in thenineteenth century.INVENTING THE LIGHTBULB:Edison’s InnovationElectric lights existed before Thomas Edison’s lightbulb,but they were expensive and often did not work. Their lightingwas also very dim. One reason is that early inventors could notcome up with a proper filament, which is the tiny wire that runsthrough the center of a lightbulb. When the filament heats up,it glows. This is the source of the bulb’s light. Before Edison,inventors made filaments from metals that would catch fire veryeasily. As a result the bulbs burned out very quickly. Other times28Invention Eureka! Files
the filament would burn so hot that the bulb would explode.Starting in 1878, Edison experimented for two years before hecame up with a charred bamboo filament. It provided 1,200hours of illumination.HOW THE LIGHTBULB CHANGED THINGS:The ImpactAs a smart businessman, Edison realized the potential inselling both lightbulbs and electricity. He quickly started a company to supply electricity to customers. In 1882 his first powerstation lit up fifty-nine homes in New York City.Almost every part of our lives has been affected by electric light. Think about all the things people do before sunriseor after sunset that would not have been possible before thelightbulb. Today, factories that would have shut down at nightcan run around the clock because of the lightbulb. The headlights on vehicles, including ambulances and fire engines, allowsafe travel after dark. And nighttime activities that we take forgranted, from sleepovers to concerts to reading in bed, would bemore difficult or impossible without electric light.The lightbulb also led to lots of other inventions. Onceelectric outlets were installed in homes, many inventors realizedthat things other than lamps could be plugged into these outlets.They then got busy inventing all sorts of home appliances—likethe toaster, dishwasher, and electric fan—that make our lives easier.Eureka!

PaperBEFORE PAPER: A Record-Keeping NightmareThroughout most of history, only a very small amount ofhuman knowledge was ever written down. Most knowledge wascommunicated through spoken words. This meant that what aperson knew was limited to what he or she could remember.One reason for this is that writing was very inconvenient.In ancient Egypt, a writing surface was made from the papyrusplant. But it was fragile. In other parts of the world people wroteon vellum, a parchment made from animal skin. But vellumwas expensive and time-consuming to produce.Almost two thousand years ago, around the year 105, a mannamed Cai Lun was keeping official government records forthe Chinese Emperor He of Han. At that time in China peoplewrote on silk, which was very expensive, or on scrolls of bamboo, which were very heavy and difficult to manufacture. CaiLun was frustrated with those choices and believed he couldcome up with a better option—a writing surface that was light,cheap, and easy to make.INVENTING PAPER: The First PaperCai Lun experimented with lots of different materials andmethods before discovering his winning formula: He mixedtree bark, old cloth, and discarded pieces of rope and fishingnets in a big kettle of boili
