Copernicus brought us a present today! Ms Honey Potts was so happy with our science investigation on finding the best material for some waterproof bears' clothes that she sent us a very cool gift.
It's called hydrophobic sand and that means that it's sand that never gets wet! At first we didn't believe it, but we tested it out and it's true! When it goes into the water, it all sticks together and it looks like it's wet but then when you take it out it's actually dry and powdery! It was very cool!
Here's a video of some hydrophobic sand in action!
