Boat launching ScienceIan and Cole

The Process of Experimenting Our boat could float the first time we

dropped it in the waterWe didn’t know exactly how we were going to

build our boat, but we knew we were going to build a balloon boat

We taped the balloon on the back of the water bottle

What We DidFirst we filled up the balloon with air and

tied a knot on the balloon We taped the balloon on the back of the

water bottle then cut the tied part of the balloon to get the air out and make the boat move
