If you ever find yourself needing to whip up some stage blood quickly for any reason at all, it is actually far more simple than you may think. Quality fake blood can be made using household products and with little financial expense to the user. This blood is also an excellent alternative to expensive store bought stage blood, and if the guide is followed correctly, it should come end up being as good if not better in quality.
1/3 cup room temperature water*
1 cup store bought corn syrup
Several drops of red food coloring
*Feel free to modify amount in order to reach desired consistency
Begin by simply combining the water and corn syrup, be sure to mix these well, as they are the most important factor in making realistic looking blood. After mixing carefully add in several drops of red food coloring, and stirring between each drop, this is to ensure that the color is as similar as possible to that of real blood. Continue mixing in drop until the color resembles that of actual blood (a deep crimson color.) Once color resembles actual blood, begin to mix in the corn starch, do not pour all of it in at once, in order to set the thickness to that which you prefer. Now, pouring small amounts of the corn starch in, test the consistency of the blood to ensure it is reaching a preferred consistency. You must consider whether you want this blood to be very runny, or thick and clingy. Once you have mixed in the desired amount of corn starch, it is best to let the blood sit for a minute or two, to ensure realism.
The blood you have now produced can be used in whichever way you desire, however, when placing it on a person, keep in mind that it will be very sticky, and it is advised not to place the blood on, or near the hair. Have fun, and enjoy!
