Please make sure the cap is on the water bottle at all times, many people seem to misunderstand that it should be on, so as a heads up, keep it on. Firstly get a very slender water bottle without a natural grove in it. Next, twist the bottle near the middle so both sides are fully enclosed from each other. Lastly, release very fast and the sudden pressure change will create smoke on the inside of the water bottle. I hope you guys enjoyed this video!
