I have a friend who filled some drums with styrofoam packing peanuts by stuffing them full through the bungs so they would float even if they floded because the peanuts will not let them fill up with water. He packed in as many peanuts as he could until it was tight and then emptied a can of closed cell foam crack sealant which swelled and made it pack solid. Maybe the right sealant and packing peanuts filling will be the right combination to use inexpensive drums in place of expensive foam filled floats.
