Build your own salt water powered V8 engine car - simply add a few drops of salt water and watch it go!
This innovative kit teaches children about new forms of clean energy. Adding literally just a few drops of salt water will start the engine running as if by magic. This special fuelled cell 4×4 car is powered from a chemical reaction with saline, metal and water. Combining science, fun and creativity, the car will tackle uneven terrain with a run time of around 7-8 minutes before it needs more fuel. This makes a fun gift for car lovers and science fans alike!
