Halloween Science: Non-Toxic Fake Blood
- by KitchenPantryScientist
Unlike the foaming green alien blood in the X-Files, the blood pulsing through our veins is red, thanks to iron-containing hemoglobin molecules loaded with life-giving oxygen.
To make fake blood that looks like real blood, you’ll need to concoct a mixture of liquid, thickeners and red pigment (tinted with blue and brown.) Kids will have a great time coming up with their own concoctions. Have a creative chemistry contest to see who can come up with the most realistic fake blood, or use it to make scary Halloween props.
Here’s a recipe to start with, but kids can work with smaller amounts and mix their blood in bowls, rather than a blender. Fake blood stains everything it touches, so be prepared for messy hands and wear old clothes! Naturally red plant pigments, like the ones in pomegranate juice and raspberry jam won’t stain fingers as much as food coloring and taste yummy. However, red food coloring will give you a more realistic color.
1/3 cup pomegranate juice (like POM) or fruit punch
2 Tbs corn starch
1 Tbs chocolate syrup (or 1 Tbs cocoa powder)
1 Tbs red food coloring
1 cup corn syrup
Tint with a tiny bit of blue food coloring. (optional)
Other ingredients to try: seedless raspberry jam, cocoa powder, Kool-Aid, Jell-O, flour, maple syrup
Here’s a fun TV segment where meteorologist Matt Brinkman was game enough to try out one of the blood capsules we made!
We made the edible blood capsules you see in the video by filling empty gelatin and vegetarian capsules with a mix of raspberry jelly, corn syrup and chocolate syrup.
