Build your own salt water powered motorcycle - simply add a few drops of salt water and watch it go!
This special fuel cell motorcycle is powered from a chemical reaction with saline, metal and water - adding literally just a few drops of salt water will start the engine running as if by magic. The motorcycle will perform straight runs, right or left circling and radical 'S' turns with a run time of around 7-8 minutes before it needs more fuel. This innovative kit teaches children about new forms of clean energy, combining science, creativity and of course fun.
