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.
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!
