Dude, I got some of those a few yrs. ago. They are friggin gigantic. I tried chucking it around some, but it's so big and heavy that it doesn't stay on top very good. You have to keep working it really hard to make it move and stay up. I still have them around somewhere, but I didn't think it was all that great. Maybe if it was 2/3 the size or floated or something.
