Question

Are those objects waterproof

Answer 1

Aluminum foil is waterproof as aluminum does not rust, but paper clips do rust, tongue depressor sticks are wood and eventually break down from moisture, rubber bands are more prone to heat and eventually lose elasticity, a sheet is newsprint is paper and paper absorbs moisture and would breakdown and masking tape loses its sticky side with water, so that should answer your question. Only aluminum is waterproof.
