The syringe generator from Arvind Gupta’s Toys was made by few students in the 6th grade. They got the required materials; syringe, enamel wire, Neodymium magnets, and a LED. The children saw the video and came up with their own syringe generator. They also noticed that the led only blinks when the magnet hits one end of the syringe every time they shook it.
