The product description says to use water, but will they work just as well in alcohol?

Not a good idea, based on this site:
Thermochromic pigment is enclosed in few micrometers size BANNED. Wall of such microcapsule is very thin. Solvents with 3 or less carbon atoms in particle (such as methanol, ethanol or acetone) should be avoided. So small particles easily penetrate microcapsule wall and destroy pigment structure – issue is colour deformation or pigment discoloration. On the other hand solvents with 6 or more carbon atoms in particle are considered as safe for pigment.
