Isn't it going to light the paper on fire?! No! The Elemental Ink disappears at 104°F (40°C) whereas normal paper lights at 451°F (233°C).
How cold does it need to get? Freezer cold works well but dry ice or other arrangements work too if you want to take it to the next level!
How it works
Disappears With Heat
Becomes completely invisible when subjected to heat. Direct flame works well but also a hit lightbulb, a hot mug of just boiled water or even an iron work too. Around 104f (40c) is the temperature that the ink starts to disappear.
Reappears With Ice
Once disappeared, the ink is completely invisible until it's chilled to freezing temperatures. Thirty seconds in the freezer works great!
This is one of my favourite trick tools to use. Your friends will be amazed too when they see the ink vanishing in front of them leaving just your secret message, or whatever you want to reveal.
Things to note
The ink appears ever so slightly grey. Because of the nature of the ink, it appears a tiny bit lighter than a normal black pen, but it isn’t noticeable unless you’re looking for it.
