Scrapathon with a twist - Building CD tanks

Based on the idea of cotton-reel tanks, families build rubber band powered tanks from kits of scrap materials and then decorate them to their own design.

Then a competition finds the family who have built the most accurate tank and who can judge just the right amount of rubber band winding to reach the target!
