Yes, you have read the title correctly; Year Five at Provo Primary have built their own salt water cars. This term we are studying sources of renewable energy, as our fossil fuels one day will be gone. Did you know that magnesium +salt water + air = electricity?
Each child was given a salt water fuel- cell car kit to assemble and then they added salt water to watch their cars race. After about 10 minutes the cars begin to slow down and all they needed to do was add more salt water and the would start up again.
What a great classroom project to learn about a potentially new way to fuel cars and they could even test different ratios of salt to see which mixture yields the greatest efficiency.
Who knew the solution to our energy needs was a simple as a trip to the beach.
