Passenger boats

Today we made passenger boats.
We used marla.
A ball of marla just sinks every time but still teacher asked us to try and make a floating boat from a sphere of marla.
We saw how big heavy shells can float if they are the right shape.
We designed boats using a similar shape.
When we could get our boats floating, we loaded them with passengers to see how many passengers each boat could take before it sank.
