People in Russia have got to be really bored. They are also not worried about whatever danger can happen to while they come up with their strange every day experiments. Here is a video that shows another use you can do with a bottle of soda, and some liquefied petroleum gas:
Apparently, according to the “scientists” on reddit, this effect can happen with any liquid and any sufficiently cold gas that gets trapped between the liquid’s surface and the air. Rapidly mixing them causes the gas to boil and expand out the mouth of the bottle, propelling the thing up in the air. Apparently, sometimes it’s so strong it causes the bottle to burst. It doesn’t look too safe, but hey, nothing fun in life is.
