Description:
The kids and I put together a neat little salt powered robot. The Green Science Salt-Powered Robot uses surprisingly simple ingredients to make an aluminum-air (oxygen) battery to operate a tiny electric motor on a small robot that you build. ... After making a super saturated solution of salt and water, you draw a few drops into a pipette and squeeze them through the battery lid.
