summary: we had to create a tinfoil boat using a 5 by 6 peice of tinfoil, 2 small marshmallows, 2 toothpicks, and 1 peice of tape. The challenge was to see which groups boat could hold the most pennies in a bowl of water without sinking.

Hypothesis:  our boat will be able to hold 40-50 pennies without sinking, if we make the sides of our boat strong then the water will not be able to flow in easily.

conlusion: our boat ended up holding 48 pennies after sinking. We came in second place. The strong sides of out boat definitely helped the stability and stopped water from flowing in.
