The way boats float is caused by how much air is inside of them. Nanogirl explained this by showing us with tin foil and rolling it into a ball, it sank! Then she had it flat and it floated! Magic? No! The reason for this is because the rolled tin foil weighs more than the water and there is also no air inside it to balance it out because air weighs way less than water. The flat one has a lot more space around it to make it float and also is not too bunched up and heavy.
The types of boats I made were. Traditional that kind of looked like a hat, a canoe that looked a lot better in the video than it did when I made it, the one Nanogirl made, and one made of straws hot glued together.
I found it hardest to make the canoe, it had lots of very complicated folds but I persevered and got there in the end. The straws one was the easiest to make because it was just hot glue.
Thank you for reading my blog. Here is my hypothesis and the results of my boats:
