What sort of materials do space ships need to be made out of? Today we're investigating the most waterproof material.
Olivia-Kate - I think the tin foil will be the most waterproof.
Marcus - I think the tissue will be least waterproof.
Niamh - We used a pipette to put water on the materials then looked to see how much water went through.
Alicia - Net was the least waterproof because water went through the holes.Eloise - Tin foil was most waterproof because no water went through.
