Styrofoam is made up of tiny polystyrene beads that are expanded and fused together to create a lightweight, fluffy material. The expansion process involves heating the polystyrene beads, causing them to expand and create air pockets within the material, giving it its fluffy texture.
Styrofoam is very buoyant because it is mostly made up of air trapped within its closed-cell structure. This air makes styrofoam extremely lightweight, allowing it to float easily on water.

Styrofoam hasn't pH.
Styrofoam is made from polystyrene, a type of plastic that is not easily biodegradable. It can take hundreds of years to decompose in the environment, releasing harmful chemicals along the way. The structure of Styrofoam also makes it resistant to breaking down naturally.
