Silicone foam

Silicone foam is a type of material that is very soft and squishy like a sponge. It is made of silicone, which is a type of rubber-like substance, and air. When you squeeze the silicone foam, it changes shape and is very bouncy. When the air inside of it escapes, the foam flattens out again. Silicone foam is used in a lot of places like in mattresses, cushions, and as insulation in buildings.
