My previous Instructable, a gumball machine fish tank, came out nicely, but had a few problems. One was the need for it to be on a stand, and another was how unstable I felt the bowl was on the base. I reworked my design and it feels much more solid now.
You will need:
Gumball machine: I prefer round, glass globes, but it's up to you.
1/4" thick glass, cut to size, with polished edges
Aquarium sealant. Regular caulk may contain chemicals harmful to fish! Don't use it.
Small tank filter
Colored glass marbles (optional)
Assorted threaded rods and nuts
Foam (for noise dampening
Rubber grommets (assorted sizes)
Jigsaw (or a lot of patience with the hacksaw)
Razor blade (for trimming dried sealant)
Step 1: Disassemble and Clean
Simple enough; take the whole machine apart and clean it.
