Interfacial Water Boiling

A group of researchers were interested in understanding how water boiled when heated within a very thin glass chamber. I created a ~ 1 inch by ~ 1 inch cuvette with 1 mm thick chamber by super-gluing glass slides together, and then used tap water and hot plate to investigate the boiling process. You can see nicely the formation and destruction of vapor bubbles. The record speed of this video was 9300 frames per second.
The cuvette was heated from the bottom using a standard lab hot plate.

So cool seeing some of the smallest vapor bubbles almost pop in and out of existence toward the end. I wonder if an even tighter macro shot and higher frame rate could reveal some cool properties during the moment of "appearing" and "disappearing".

Just looked at the raw data, looks like ill need 10x higher fps to properly characterize that physics... bubble nucleation is super fast!.... to do that bit right, ill dial up the magnification, and push up to 500 kfps. great suggestion!

@@kdgilroy4 You still have the 7510 model available to you? Could be cool!

[@kdgilroy4]

👍 definitely the choice

Interesting. Was the hot side on the right? The bubbling seems to start there.

great question, from the bottom!

Looks like water becomes hydrophobic!
