This is my rubber band pitch car
It has great water bottle support to keep it stable, it has 4 CDs to help with transportation, it is duck taped to stay stable, and there are 2 straws are attached to the bottle to keep it from falling apart.
I might think of adding some more tape because I'm not so sure it will become more stable than it is now.
1 Water Bottle ($10)
2 Straws ($8)
4 pieces of Duck Tape ($8)
4 CDs ($20)
