A science teacher and YouTuber mixed chemicals together in tiny science equipment to make satisfying sounds in Gosford, Australia.

Boiling water in a small flask is turned upside down, which sucks up the contents of a beaker to create a mini water fountain, all done in front of a microphone to create an ASMR effect on June 19.

In this Tiny Science ASMR episode, Australian Science Teacher uses a tiny bunsen burner to heat a small amount of water up in a conical flask. Once it has boiled for a short time, the flask is inverted and the tube placed in a small beaker of water. As the water in the flask condenses, a vacuum is formed, and surprisingly water is pushed up into the flask just like a miniature fountain.
