Tent investigation

We have been investigators again, this time to find the most waterproof material to make a tent for James Bear.

We investigated some net, tin foil, cellophane, kitchen roll, plastic bag and apron fabric.

We used a cup with a hole in the bottom. Next we placed the material over the top. We stood the cup on a paper towel. 

Then we dropped some spoonfuls of water on the material. 

The plastic bag, cellophane and tin foil were all waterproof but they were not strong. A bear could attack you in a tent made of these! 

We knew the best material because it would not let any water drip onto the paper towel. 

The best material turned out to be the apron fabric so that is what James should make his tent from. It is waterproof and strong.
