Build your own salt water powered V8 engine monster truck - 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 fueled cell 4×4 vehicle 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!
Eight year olds like more challenging construction sets, and are starting to get seriously interested in science. Anything involving potential explosions or high speed makes a good present. They can also start doing cleverer magic and love doing tricks. And anything they can throw or shoot at someone else is also very popular.
