A super cool project, this is what I'd like to share with you. This is a science theme that will probably appeal to a lot of kids. You can make small cars race on salt water... how much fun is that? Host parentIneke van der Linde saved this cool set up through the Shell (not sponsored) Now the time was there, and they went to do this fun activity with the BSO kids. Read the story of Ineke below.
Ineke tells: I wanted to perform the theme “Driving on salt water” with my BSO group for a long time. It had not come of it for several reasons. This summer I came across this beautiful savings campaign. Of course you can save more/less.
What you see here in the photo we used for a delicious BSO afternoon.
The parts for the racetrack are made of cane sugar. It is at the same time an educational and sustainable project.
First, we build the race circuit together. We do this by connecting the circuit parts with wooden connectors. That's just a patient job, but by doing this first, everyone is completely focused.
Next, a saltwater mixture is prepared by the boys. First the salt to half the tube into it. Then carefully top up with water. Shake the whole thing a lot. Well, with your thumb on it.
Then attach the battery with the metal plate in which the energy is stored to the bottom of the race car. As soon as this comes into contact with the salt water, the energy is released!
Put the race car back on its wheels, fill both holes in the race car with 3 drops of salt water mixture each. You can do this very conveniently with a pipette. And then it's time for RACING!!!!
You can make an oval race track or an 8 or a completely different figure. This depends on how many track sections you have.
If you want something else, you take one piece and let the cars jump! And they drive hard on saltwater.
If the car is run OFF and you take the battery out again, you can see the difference very well. The new battery still has clean pictures. The battery used has metal plates that are acidified.
Watch the cool video of the salt-racing cars!

Below are 3 different Science projects where salt is also used as fuel.
