Can I use superglue for a DIY fountain project for my FBT?

Building it outside with silicone as Bill suggests is a good idea, when it doesn't stink like acetic acid then it's cured and ready to go in.

Silicone from Home Hardware (it's also sold individually) Home Hardware - 3 Pack 300mL Multi-purpose Clear Silicone II Sealant They also sell the guns to hold the tube, but unless you need to finely control the application you can just use a stick as a plunger if you want to go cheap. It's worth getting a gun if you're going to be using silicone often though.

I'm also a fan of dollar store super glue, it's not a big loss when the tiny tubes get gummed up or glued to your fingers.
