Science experiment - Non waterproof Led Strip underwater

Today I just made an experiment out of curiosity. I wanted to what happends when I submerge a led strip in normal tap water, which is not waterproof and does not have any ip rating.
Conclusion is not to be trusted and only from my knowledge I got from school.

Cool test! The bubbles are more likely due to electrolysis of the water rather than oxidation (although oxidation will definitely occur). 12V is more than enough for the electrolysis of water, and the resistance of the water is high enough to not increase the current draw. I just tested with my power supply at 12V with bare leads quite close together in a glass of tap water, and it showed 0.00A current, and small bubbles started forming after a few seconds.
A dab of silicone over each LED and resistor will likely work extremely well to mitigate any damage longer term. Perhaps even just some conformal spray would work, although that can sometimes weather off as well.

Thanks for the insight!: did not think of hydrolysis but I am pretty sure you’re right 👍
