You would think so. The gimmick of it is that you flip it over to get the worms out since they gather at the bottom. I got soaked the first time I wet the bedding because the water poured right through it. Had to take the bedding out and dampen it in a little bucket first, then put it back.That would work for livers... just add ice! Also styrofoam works great for minnows because it "breaths" allowing O2 into the water.
