waterproof nontoxic adhesive?
I'm looking for an adhesive that will bond plastic to plastic, is waterproof, and is also non-toxic. I am attending an "anything but cups" party and am planning to use a Magic 8 Ball. I know that there is a canister inside which holds the die and blue liquid. I believe in order to take that out, I need to open the entire ball. I don't think that it will snap back together in a way that won't leak. Any suggestions would be appreciated!
