I had bought a car kit on clearance a few months ago. It looked too complicated for me so I planned on bringing it home to have my husband put together but I had forgotten about it in the back of my closet. A few weeks ago one of the students spotted it and asked if they could put it together. I was a little apprehensive about parts getting lost but I went ahead a let them. Wow! I was blown away! A team of three of them had that car put together in about 10 minutes. I was very impressed as it had many parts and a batter-run light. Great job kiddos!
