MAEKUP Foaming Mouth 30g
Another great product from Dave Stoneman, the Maekup Foaming Mouth is a powder that-- when activated with saliva-- forms a foam that is great for simulating zombies, rabies, rabidness, etc. To use, you place a teaspoon of the powder in your mouth and allow it to foam with your mouth slightly open. Then close the mouth and eject the foam during the take as required. Be sure not to swallow the foam, though! Rinse the mouth out and repeat for each take needed.
