I don't think I've ever worked with something that defies the way my brain works. Seriously. I watched Tree Ninja put together two cages, and my mind could not comprehend how quickly it secured the sides of the cages. Super glue, eat your heart out. It's fascinating to see these panes of glass standing up on another pane of glass underneath it and held up by only tape and silicone until the silicone is cured. But that stuff works! Give it like 5-10 minutes and silicone will bind the glass together better than any kind of glue in the stores.
The whole tank even as it's put together, is held up by the still-hardening silicone. It can hold the glass up effortlessly while at the same time still be finishing the curing process. Wild. Just wild.
