Crusty white temporary hair color spray?

Okay, so this Wednesday I want to dye my hair white (cause I think white hair is awesome) with temporary hair color aerosol spray (Fun and Fantasy) we have left over from Halloween costumes and stuff. My Mom says that that stuff makes hair really crusty and sticky and stick-togethery(ish), etc. Is there a way to make it not do that? It kinda smells funky to and I am going to be out with my youth group and I don't want to kill them with it (If that is possible) I will also take other options that I could for a TEMPORARY color and no I will NOT bleach my hair. But I am very open for any other suggestions, LOL.
