Fake Blood Recipe
We made two types of fake blood. The first shows and demonstrates how blood actually works as it clots.
The second is just pretty cool and more effective looking!
Both contain food colouring and stain clothes, so make sure you aren’t wearing anything you’re not happy to stain red!
