Can a paper boat float?
This week in 'My World', we tested different materials to see which would make the best boat. 
The paper boat quickly got very soggy and fell apart.
The plasticine sunk to the bottom. Some of us could make it flatter and it stayed up for a bit.
The wood floated and could carry some little characters on it like a raft.
The best ones were the plastic tubs, they could float on the water and the small characters could sit inside.
We found that to make a good boat, the material has to be waterproof and has to float.
