Those of you with tubs but no racks. How do you keep your snakes from getting out. Do you use straps? I'm sure that my ball could pop the top on those plastic tubs.

If you have more than one tub...do you put the tub right on the heat tape? Then stack another on top, more heat tape, then tub, etc?

I understand the rack system (I'm getting one this summer) with tubs just not tubs without the rack...
