I am so excited! I finally did it! Just wanted to share with you all how I did it. (thanks to a cake contest show for the inspiration!)
It will glow under a black light.
I used clear piping gel. Heated that in a sauce pan. Added tonic water (the ingrediant that will make it glow) I used this for slime on a Ghostbusters cake so I used enough tonic water to make it very thin. I added my coloring at this point. After heating it very well I added plain gelatin. Let it set for 2 hours and it was thick enough to spoon over the cake for slime.
The possibilities are endless. I made another batch later on that was thicker. Like the piping gel that wilton makes. A side note tho, the slime appeared to "eat" the fondant after a few hours. It is something that you want to wait to put on.
I loved doing this cake. It was a mess but so fun. The boys loved it!
I couldn't attach a photo so here is the link for the Ghostbusters cake I posted today.

I tried to do that for a quinceanera cake I did yesterday and it didn't work for me. I only used the piping gel and the tonic water. I guess it needs the gelatin. I will try it like that next time though.
