Stir some flour or white frosting mix into some clear
Karo syrup until it looks cloudy. Then mix in enough red food
color to get a good blood color. If too thick, add a little
water. If too pink, add more red. If too transparent, add
Powder surface of grease paint to prevent blood from
gathering into drops. Or, scratch off grease paint in area
where you want to apply blood. Or, work up a little lather on
a bar of soap and paint a film of soap on the surface.
