You can mix mica or other powdered colorant (you can get them at places like hobby lobby) or a fine glitter with cornstarch for a pixie dust for body. Dd loves this... though at 13 I'm not sure if they go for "pixie dust" or just body glitter... I'm sure you'll all have a great time though!

Thanks mamas, my DD LOVES all the ideas.
*Especially* the pixie dust - Tinker Bell has made a come back, we actually just redid her room w/ tink stuff, and were making a castle cake w/ tink on it
