I'll imho, assuming that seriously bubbled water has the same characteristics as normal water can be quite deadly. I think that some naval research once looked into blowing air out of the hull through many holes to make foam around it that would *reduce* resistance at high speed. Me, I'd not jump into a bubbled pool, even if 5 times deeper than the clear water kind. You can't see inside, in the first place, and you can't know if you will *float* at all. Probably *not*. Peter
