Fake Blood Recipe for Forensic Science
We will be using fake blood in our blood spatter analysis. We can’t use real blood because of the risk of blood-borne illness carried by human and/or animal blood.
This fake blood recipe is from special effects, Halloween props, or vampire websites (for when you want to be a vampire, but think real blood is gross). Our goal is to make fake blood that matches the consistency of real blood. It’s easier for us to visualize the consistency when the appearance also looks like blood, which is why we use food colors to try to match the color of blood.
**All these STAIN clothing! Please be careful mixing!
Realistic Chocolate Blood
½ cup water (warm)
1 tbsp cocoa powder
3 or 4 tablespoons corn syrup
½ - 1 tsp red food color
2 drops green food color.
Mix cocoa completely into warm water before adding other ingredients. Add other ingredients, blend well. Wait 5 min for it to settle. Skim the bubbles off the top with a Kleenex.
Best Forensic Science Videos for Blood Spatter Unit
The Killer's Trail
This details the Sam Shepard case. The movie The Fugitive was loosely based on this case. Dr. Sam Shepard was tried and convicted for the murder of his wife. He claimed that someone else did it. I like to have students watch this video, then do a lab where we recreate this crime using a "dripping weapon" and a "bleeding wound."
Unfortunately, this movie is out of print, and very hard to find on DVD. If you can find a copy, grab it! It's a great one to use with this unit.
Forensic Files: Where the Blood Drops
This is the Susie Mowbry case. The forensic evidence includes blood spatter and blowback from when a person is shot with a gun.
