Remember there are two types of foam. Closed cell and open
cell.
Closed cell contains individual bubbles which are closed.
This type will not absorb water.
Open cell is really a network of foam which has air space
inside it which is contiguous. This type does absorb
water. Most sponges are open cell.
I have no idea which the Europa blue foam is.
It is dark and rainy so I won't go out to my shed and look
tonight !
