~10 and 15 amps run though resistance wire submerged in water. A thin film boiling regime can be seen in the second clip. The reduced heat transfer coefficient results in excessive heating of the wire not found in the nucleate boiling of the first clip.

Really interesting flow setup and the pattern in your flow
Hunter, this is awesome!! I would have never thought to try this — very interesting use of science and engineering to create some amazing visuals, and you did a great job capturing it! Nice work!
Such a great experiment. I really like the difference between the two videos. Both are intriguing in their own way with the different bubble formations.
This is a really cool experiment and made for a great video of flow visualization. I really like how you included several different shots as well.
This is an incredible video! The visuals are amazing, and this is such a cool thing to watch in slow motion. Phenomenal job!
This is just beautiful to watch. I like how you showed the setup before running current through the wire so that we could see the initial bubble formation. This showed the contrast between the stillness and then the bubble formation after turning on the current. I also really enjoyed the bubble formations themselves. Additionally, I thought it was neat to see the two different experiments back-to-back so that we could compare them.
I really like the idea and the crisp video you got from it! Great Job!
The pattern that the bubbles settle into is amazing!
So sick that you thought to do this! Looks real neat, excellent work!
