How to make fake blood

Chocolate Blood (edible):


  1. combine light corn syrup with red food dye until you get a shade that closely resembles real blood. you can also use a red drink mix(like cherry cool aid powder) instead of red food dye, although be warned this changes the flavor. 

  2. carefully add a small amount of cocoa powder to the syrup mixture to darken the shade and make the blood opaque like real blood. 

  3. finally you can either


  • thin the blood by adding water 

                          or


  • thicken it with a couple pinches of flour or cornstarch mixed in carefully and slowly.

this mixture look great, smells great and tastes like chocolate.

                                    or

Movie blood (inedible):

  1. pour about 3/4 as much alcohol - free, water-soluble hair gel as the amount of blood you want.

  2. add water-soluble motor/radiator lubricant, any brand. this should be semi-opaque and slightly thicker than water. start off with a very small amount and mix the gel until it turns watery.

  3. mix in about half as much food coloring as there is liquid. preferably, buy a "super strength" type at a bulk foods store to save money, and skip cheap, 1oz bottles, they look too pink. 

  4. add small amounts of chocolate syrup to make the blood more brown , and improve the thickness. it shouldn't be too much like water, but still very dribbly. 

  5. add small amounts of hand sanitizer if you're having trouble  with a nice, drippy consistency.

                             be warned, this weakens the mixture easily.

6.  check the mix. the final mix should be a little bit thicker than water, deep brownish-red, and  opacity of milk. unlike the non-toxic blood, it will not be sticky. when dribbled from about five feet, this blood will create nice"spatter" patterns, like real blood does. on skin it will flow easily and smear like the real deal. but, be careful how you use it. it can easily get everywhere.


bleeding marvellous:

what you'll need:


  • red food coloring or fake blood

  • dropper

  • small beaker

  • plain paper

  • ruler

  • metre rule

what to do:


  2. lay out some paper to protect the floor, then place the paper you'll drop the blood onto on top of them.

  3. hold the dropper 10 cm above a clean sheet of paper and drip one drop of blood onto the sheet.

  4. measure the distance of the spatter, making sure to write down the height it was dropped from and the diameter of the spatter. 

  5. drop the blood from 20 cm higher each time until you get to 200 cm or higher if you wish you can go up in larger or smaller amounts.

  6. measure the diameter of the spot and write it down as well as the height it was dropped from.

  7. use a new piece of paper to drop the blood on every time you change height (this will avoid confusing results.

  8. make sure you're measuring the distance of the spatter each time you drop the blood.

  9. once you have done this, get someone else to do a spatter at a distance of their choosing from 10cm -200cm.

  10. make sure whoever conducted the test originally can't see the random drop, because their task now is to work out what height it was dropped from by measuring its spatter and comparing it to their results from before.

  11. if they have recorded their results accurately then they should be able to guess what height the random drop was dropped at.
