Can anyone here share their recipes for great fake blood? I have read various recipes using Karo syrup with food colouring. I'm sure this works great but does anyone have any fake blood recipes that may not have something as sticky as syrup as the base? I would like a fake blood that stays nice and red, that doesn't dry and flake off by the end of the night. Also would like it for my clothing, definitely willing to do a couple different formulations if one that is great on clothing isn't so great on skin, etc. Different tried and true recipes with the pros and cons for them would be greatly appreciated.
