1. plastic cups
2. paper
3. straw
4. tin foil
i was in a group with Willem my best friend. our design was two cups taped together and two on the side there was a little spot for the marbles on top made out of tin foil.
it held up well but it did not fit as much marbles as the other kids did but i was happy. i think next time we would Chang the top and put more room for marbles. thank you for listing.
do you think you would have won.
