Designing boats

Did you know that a ball of marla sinks?
We tried this out and it is true.
Teacher gave each of us exactly the same sized sphere of marla.
We had to make a boat that could float.
When we got our boats to float teacher gave us passengers (dried peas) to put in to our boats.
We had to try and load the boat with as many passengers as we could.
The winning boat was able to take 24 passengers before it sank!
