In this video we follow a paper that describes achieving a daytime radiative cooling effect on cotton fabric through the growth of CaCO3 microspheres directly onto the fibers. The paper can be found here: doi.org/10.1016/j.compositesb.2022.109988

Cutting steel with electricity and water. Ive been playing with how to this method for the past few weeks and am having some trouble, but I know its possible.
Check out this video to see where I got my inspiration: https://youtu.be/jEnNMTMZadw
I tried this same method at one point a few years ago and had better results than I have so far been able to replicate in my latest experiments. Possible causes that Im considering:
1. The metal etching paint formula has been changed
2. Paint requires a longer time to cure
3. Baking soda is not an acceptable replacement for salt (I used baking soda in these latest tests because it does not produce chlorine gas as NaCl does)
Let me know what you think in the comments below!
