In this video, Youtuber “The Action Lab” showcases a really interesting high-molecular weight polymer that can self-siphon and pour itself our of a beaker. The reason it can do this is because it can be made to have a very high molecular weight. The solution in the video has a MW of 1,000,000 while water has only a MW of about 18.
The solution he used had a MW of 1,000,000. The solution is basically like a molecular sized bowl of string or beads that pull each other out of the beaker once the initial pour has started. Polythylene Glycol is also used as a laxative. It is very slippery feeling like mucus and once it is on your hand it is tough to get off!
