Ok so since I hit the front page :squee: I have had a LOT of people asking the same questions, so just a quick FAQ for y'all to make life easier :) I'll add to this as more questions come along!
How do they GLOW??
Magic ;) which is provided in the form of a nifty little compound called strontium aluminate. This is the standard glow compound used all over the world. You'll find it in toys, watch faces, emergency signs... It's completely safe and non-radioactive.
How long do they glow for?
Answer: It depends on the colour!
:heart: Red :heart: is the worst glow colour around ever. Although I have timed it glowing for over 3.5 hours so far
