I tried this 50+ years ago, but with no tubing. I poked a hole in the metal bottle cap, but forgot about the cardboard seal. The glass bottle blew up in my hand and I had to have a few pieces of glass dug out, then a few stitches to the cuts. x-rays of my fingers were negative for broken bones. And there was a 3 inch crater in the window box dirt ousting my bedroom window.

Almost want to try it again just to prove I am still an idiot.
