“SALT WATER POWER ROBOT” Green Science Kit Description:

Powering the world with salt water, one robot at a time!

Peek into the future of clean energy! Build your own miniature robot racer powered by salt water!

The 4M Salt Water Power Robot Kit provides all the materials needed to assemble this environmentally-friendly, non-toxic robot.

When your robot is completed, insert the included aluminum and carbon sheets and simply add salt water. No batteries required!

Watch gleefully as your mini robot whizzes across your floor!

The kit supplies two sets of battery sheets. Each set will power the robot continuously for up to an hour. Or, stop the robot before the energy is drained by removing the battery from the battery case. Wash, separate and dry the sheets and reuse the battery sheet another time. Additional battery sheets can be ordered from the manufacturer.

Detailed, illustrated instructions also include the science behind aluminum-air batteries and interesting “fun facts.”

Teach alternative energy the kid-friendly, fun way with Salt Water Power Robot! Great for science fair projects too!

Salt Water Robot is a 4M Green Science Kidz Labs product. Green Science kits encourage environmental awareness by introducing kids to green concepts such as repurposing, upcycling and alternative energy in a fun, do-it-yourself way.
