How to Make Fake Snot! (Not Borax/Glue Slime)…
Now, you may have seen the borax/glue recipe online. This is kind of different. You’ll need: saucepan/bowl, stove/microwave, three packs unflavored gelatin, food coloring (optional), spoon, light corn syrup, extra bowl, resealable plastic bag.
1.Pour 1/2 cup water in the bowl (if you’re using a microwave), or saucepan (if you’re using a stove).
2.Heat the water just until it boils, then remove the water from the heat source and turn it off.
3.Sprinkle the gelatin in the water. Stir. If you want to add food coloring, do so now. (But I wouldn’t put any color if you want it to be realistic).
4.Let the mixture sit for one minute.
5.Measure the mixture as you move it to the extra bowl. Remember that amount, and add enough corn syrup to make 1 cup total in the bowl.
6.Stir and lift out the long strands of snot you’ve made. If the snot thickens as it cools, add water spoonful by spoonful to thin it. Store in a resealable plastic bag. (Never pour slime down the drain. Put it in the trash to get rid of it).
WHY IT WORKS: Water causes the gelatin molecules to cross-link and form a polymer. All polymers are made of many chains of identical molecules, connected by bridges called cross-links. So, lots of polymer/slime recipes will give you flexible, stretchable slime. But corn syrup makes this slime especially snot-like!
