FrenchCrawler shows you how to make some spooky water for your Halloween project(s) – “Looking for a new way to spook your trick or treaters? Maybe you have a haunted house that needs some added effects. Whatever your reason is, this is one way to creep people out.

I did this by accident when I was younger. I was playing with my blacklight and some highlighters (writing out secret messages and what not) and the marker I was using was starting to dry up. I usually just wet my fingers and use them to wet the tip, but someone had left a small glass of water on the table so I instead dipped it into there (kind of reminds you of a feather and inkwell). After a while the marker would start to go dry again, so dipped it again….and again. I decided to let the marker soak up some of the water in hopes that it would last a little longer so I placed it in the glass and switched over to another colored marker. After about 5 or so minutes, I looked up and saw the water “glowing” a little. I placed my light closer and it started to really glow. That’s when I discovered that highlighters make really cool effects when used in water.” – Link.
