Have fun in the sun with solar cars!
Its a simple way to learn about renewable energy in an exciting way.
There are three cars per pack, each including a solar panel, so all you have to do is find a patch of sunlight, sit back and watch them go for a run.
The small cars move off at high speeds as soon as they come into contact with the direct sunlight, and then come to a shuddering halt when they go into the shade.
Absolutely no other power sources or batteries are required.
They are an ideal eco-friendly gift as well as a great introduction to solar power and renewable energy sources for young people. |
