Okay! This is my first tutorial, so please bear with me.
You will need:
Hi-liters, preferably yellow. I used one “jumbo Style” marker, and one more slender marker
Pliers. Any kind will work
A jar to hold your ink.
small cups. I used 2 disposable ones.
Eyedropper, it’s pretty useful to have it on hand.
Black Light. Blue light works too, hence the Wheatley, but a black light is preferred.
(Not Pictured) Newspaper. This can get messy if you are not careful. I was not careful and so am now very yellow and glowy
(Not Pictured) Hot Water. Just as warm as you can get it from tap works.
Now go forth and make some invisible ink!
