 How do you think I got my board to work under water? Well, it's not actually water. It's mineral oil. I wanted to do an experiment to see if I could water cool my electronics. First, I tried water, which, as expected, fried the board. It actually smoked under water and when I took it out 30 minutes later, it was burnt to a crisp. So when I tried mineral oil, which doesn't conduct electricity, the board worked just fine. Want to see more stuff like this? Check out the YouTube channel in the bio.
