Are materials waterproof, or absorbent(do they soak up water well)?

These are the materials we tested:
Cloth, sponge, tinfoil, tissue, plastic, newspaper, ourselves.
We found out that cloth, sponges, tissues, and newspapers soaked up water really well. They are all absorbent.
Tinfoil, plastic and our hands do not soak up water at all. They are all waterproof. We had fun testing to see which belonged to each group
