2 paper cups
2 straws
duct tape
Some boats floated but others sank.We stuck the two cups together and put the straws at the bottom. We used the duct tape to sticks the objects together. Different groups did different methods but most of them worked. We tested them out in a basin of water. We used coins as passengers. We had to see how many passengers our boat could hold.
