I got some, since you mentioned liquid latex.

Puff out your cheeks as much as you can then apply latex to them. keep your cheeks puffed untill it drys and release. Instant wrinkles.

This one's cool, apply a layer of LL and then put a piece of single ply tissue or toilet paper on it and let it stick. Tear off the excess and apply another layer of LL. (you may want to apply 2 or 3 more layers to get a good thickness.) After all that dries, find some cheap makeup that matches your skin and apply it to the latex, and set it all with some colorless powder (3.99 for a little jar at your local halloween joint) Now you can do whatever you want with it, tear it, cut it, or my favorite, get a medical syringe, fill it with fake blood and CAREFULLY slip it under the appliance. Then release the blood and seal off the part you lifted. Vola, a giant blood blister you can burst in people's faces!
