One idea I had was to use this to dress up as blue man group. If any one wants they could write a guide because I don't want to use it if I'm just going to fail miserably!
I think it would be a funny idea to do though, I haven't seen one before
I used to work for Blue Man Group in Boston as their make-up artist. That's exactly what we used to use, and the instructions look great too. I guess the secrets are out of the bag!!
I'd probably add "Keep out of direct sunlight" (just for those who get it)
