Waterproof and non waterproof

Today we talked about objects and materials that are waterproof and non-waterproof. We investigated and tested objects. We discovered the umbrella, welly boots, plastic bag and glass jar were all waterproof. The water did not go through these objects but slid off them. Then we discovered paper, newspaper, a sock,  tissue were not waterproof. The water ran through them. So it is very important we wear waterproof clothes and jackets if we are in the rain and use umbrella's to keep us dry.
