You and me, baby, we've got chemistry! Dump the stuff from the test tube into the Erlenmeyer and watch the reaction change colors ;-)
The color change is the magic of Masura 294-244 and 294-247, both thermal gel polishes that you can see in their full glory in my Masura review from 2016. They change from yellow & green when warm to pink & purple when cold, making them perfect for some cool nerdy chemistry nail art!
I received Masura 294-244 & 294-247 as a press sample. Opinions expressed are 100% my own and not influenced in any way other than the quality of the product itself.
