Hey kids! Want to impress everyone on your block with the coolestscience project ever! Then this weekend project is just for you. With thehelp of your parents you can create your very own Van de Graaff generatorand make your hair levitate with the help of science.WHAT IS IT?A Van de Graaff generatoruses a moving belt thatcarries electric charge up to ametal dome. This is a lot likewhen you rub your socks ona rug and collect charge thatyou can use to shock people.In this case when you touchthe dome the charge flowsthrough your finger tips andto the ends of your hair.Since the charges are thesame sign they repel eachother like when you try topush two magnets togetherwith the same magnetic side.Figure 1.

INSTRUCTIONSNOTE:PARENTALSUPERVISION REQUIRED10
MAKING THE BASEFigure 2. The base of the Van de Graaff (24)1. Connect the narrow end of the PVC coupling with the 1 ½ inchend of the PVC Bushing.Caution: Parental Supervisionneeded for the following step.2. Cut about 2 inches of the 1 ¼ inch PVC pipe and insert it intothe 1 ¼’ end of the PVC Bushing.11
3. Connect one of the 1 ½’ ends of the tee connector to the freeend of the 1 ¼’ pipe.Caution: Parental Supervisionneeded for the following step.4. Cut another section of 1 ¼’ pipe about 15’ long.PREPARING THE MOTORFigure 3: DC motor wrapped in electrical tape (25)1. Wrap electrical tape around the shaft of the motor to graduallyextend it.2. Wrap the body of the DC motor with electrical tape to snuggly fitwithin the outward facing Tee opening.12
3. Thread the rubber band down the top open end of the Teeconnector and around the shaft of the generator.PEPARE THE FUSECaution: Parental Supervisionneeded for the following step.1. Use pliers to hold one end of the glass fuse and hold the othermetal end of the glass fuse over a lit candle.2. After 30 seconds remove the glass fuse from the flame and use thepliers to wiggle off the exposed metal end of the fuse.3. Remove the wire within the fuse with the pliers.13
DRILL HOLESCaution: Parental Supervisionneeded for the 3 followingsteps.1. Drill a hole just in the PVC Tee just above the shaft of the DCmotor.2. Drill a hole about 1’ from the top of one end of the previously cut15’ long PVC pipe section.3. Drill another hole just below the previously drilled hole14
THREADING TOP ASSEMBLY1. Thread one end of the bamboo skewer through the farthest hole fromthe top of PVC pipe. (Make sure not to the thread the skewer all the waythrough the pipe)2. Now thread the glass fuse through the skewer.3. Pull the rubber band through long section of pipe and around the glassfuse. Now feed the skewer all the way through pipe and fit the pipe inthe tee connector.4. Hot glue the skewer in place.5. Cut a 5’’ length of wire and strip one end of the insulation. Insert thebare end into the base through the drilled hole. Make sure the strandsare spread out and the wire is close but not touching the rubber band.6. Cut a 2’’ length wire and strip both ends to.Now feed one of the wirethrough the remaining hole just above the glass fuse and rubber bandassembly. Like the bottom wire, make sure the strands are spread outand close to but not touching the rubber band. For now secure the otherend of the wire to the pipe using electrical tape.15
SODA CAN1. Get an empty soda can and remove the lid using a can opener.2. Attach the other end of the top wire strand to the inside of theAluminum can using electric tape.3. Place the can over the top of the PVC Pipe and take down withelectrical tape.BATTERIES1. Place the 4 AA batteries in the battery pack.2. Connect the battery pack to the 9v battery snap collector.3. Connect the loose ends of the battery snap collector to the DC motorterminals.16
