Float your boat science lab

Name: Jake BLK:D

CHALLENGE: Make a boat that can float in water and hold the most amount of pennies.
PROBLEM: What is the best design to hold the most weight with the materials given above water

HYPOTHESIS: If I put pennies on my boat then the pennies will not sink

IDEA FOR ORIGINAL DESIGN:

 
My group chose this design because we think that the marshmallows will hold the boat up evenly and make it float while the crossed straws will give the tinfoil support.
HOW MANY PENNIES DID YOUR BOAT HOLD? My boat held 130 pennies

WHAT WOULD YOU KEEP OR CHANGE ON YOUR BOAT DESIGN IF YOU WERE TO DO THIS AGAIN? If I were to recreate my boat it I would make the walls of the boat taller so the water is kept out longer. I would keep the marshmallows on the 4 corners because the really helped the boat float.
