This fun science kit is designed to excite and engage experimenters of all ages in re-creating the development of the first light […]
Litiholo Hologram Kit
Making holograms became faster and easier a few years ago when Litiholo introduced its Instant Hologram film. Like old Polaroids, these film plates require no developing after exposure, which means, in about an hour, you can make your own transmission hologram of anything that will sit still next to the plate. The kit also includes […]
Laser Voice Transmitter and Receiver

The receiver is just an earphone and a solar cell; no power source. I assembled both in minutes, and it was strange (in a good way) to hear music […]
Energy Wiz
Aimed at kids 8 and up, this kit has real heart. Its 48-page workbook and components (solar cell, buzzer, two motors, LED, capacitor, copper rivets, pinwheel, etc.) take you through lessons and fun experiments that teach the basics: What is energy, as distinct from force? What forms does it take? How can it be converted […]
