Foaming Alien Blood
- by KitchenPantryScientist
If you’ve ever seen the X-Files, you know that foaming green alien blood is pretty scary.
It’s simple to use kitchen table chemistry to mix up your own batch of green alien blood with corn syrup, green food coloring, water and baking soda.
Just add vinegar (tell your friends it’s water) to make it foam.
Mix together:
2 Tbs corn syrup
1 tsp baking soda
green food coloring
1/2 tsp water
When you want to make your slime foam, add a few tsp of vinegar.
You could make the same thing with red food coloring and call it vampire blood!
The Science Behind the Fun: When you add baking soda (sodium bicarbonate) to vinegar (acetic acid), there’s a chemical reaction that creates carbon dioxide gas bubbles!

Halloween Science: Magic bags of “Blood”

Create instant Halloween fun with some zipper bags, food coloring and wooden skewers!
Plastics are polymers (long chains of molecules, like beads on a string.) Some polymers, like the ones in plastic bags, are good at stretching and forming seals. When you poke your skewer through the bag, the plastic forms a seal so it doesn’t leak. The forces of surface tension are also at work to keep the bag from dripping where you’ve pierced it, since water molecules really like to stick together.
