Hi All, having a few kids over this weekend for some fall arts and craft. One activity will be paint pouring over pumpkins. I've seen a few youtube videos and so many people use different things such as Floetrol, liquitex, silicone, water, glue to add to the paint. I don't want this project to cost me a fortune as I'm having around 15 kids. I would like to mix the paint with liquid pouring in cups so the kids are ready to go. Anyone know ratios and how to simplify so I can make this as affordable and simple as possible.

Any art teachers here??
