I am doing some finishing touches on cupcake toppers for a children's party and want to do some painting on them. I usually paint with Vodka. Is this ok for a children's party? I always thought the alcohol would evaporate off, but I want to make sure before I do it.

It will be fine. The alcohol will evaporate and be completely safe for the kiddo's.

I agree, it will evaporate. However, you can always use lemon extract.

I use clear vanilla. It does get thick though if you take a while as it evaporates.

I've used everclear to paint on my cakes and there hasn't been a problem as the everclear is so high in alcohol, it evaporates extremely fast (which is great, 'cause it dries quickly making it easier to keep working) especially here in Houston. I don't like to use clear vanilla or the lemon extract as they aren't always compatible with the rest of the cake.
