I'm doing up a fancy multi-tiered punch bowl with a small aquarium

will be held in place by a plastic fitting, so the sealant need not be
strong, just prevent leaks.

Take a look at the DOW 732 products on this page. Read the second to
last sentence in the description below.

plastic, ceramic, glass, natural and synthetic fiber, silicone resin,

vertical surfaces. Begins to harden in 20 minutes. Temperature range

Oh, just go to a full-line rental store, and rent a real one. Same place
that rents chairs and pergolas for outdoor weddings should have it.
Do you really want to risk somebody getting sick if you screw up? Or
risk the wrath of the SWMBOs involved, if the thing starts piddling on
the table halfway through the party?
