THIS IS SO COOL!!!

Oh my god, wow!! So fast! I've never seen a thermochromic material change phases that quickly.

I think because the concrete has really high thermal conductivity. Why stone feels cold etc etc. Cheap amazon pigments and quick cement lol

Would be really interesting to see a thermochromic ink option for PCB screenprints

Seems like its not that intrusive to add to white silkscreen. Maybe a trivial mod!

WHAAAAT

Writeup in case u wanna try

Mechanochromic is super cool too. The actual strain on the polymer chains or crystals causes color change. 🤩

Looks dope, what did you mix into it?

I need this
