Would this work well as a rack?

[snakesRkewl]

On a shelf, any wood shelf. The tub just sits on the flexwatt.

Do not trust locking lid tubs to hold snakes in without something holding the lid down(not books!!)
I see bookshelves like this for $5 at garage sales and even goodwill occasionally.
After losing a few snakes that were in tubs sitting on the counter top I decided enough was enough, no more tubs without a rack of some sort...
