Rubber Band Racer - crawler

Remake of a classic rubber band racer (Thread Reel Tank). Rolls pretty good on carpet. But for a smooth floor you would need to put some extra rubber bands on each of the wheels, they have slots for that. For a better friction you can put a bit of WD40 between the body and wheel. To add friction and slow it down, you can add hand soap (classic :))
Not for little kinds, because it has small parts!
