How to Make Slime

Materials:
Bowl
Spoon
1 Cup cornstarch
1 Cup of water
Green food coloring (optional, other colors can be substituted)

This recipe makes the thickest slime. It looks less like snot than the other recipes. Add the water to the bowl and pour in a few drops of the food coloring and mix together.

Slowly stir in the cornstarch mixing it continuously. It will thicken as you add more cornstarch. Keep adding cornstarch and mixing until your goo reaches the desired consistency.

This slime acts like a colloid. It will be more liquid as you stir. When you stop stirring, it will become more solid. More water can be added as necessary.

Materials:
Bowl
Spoon
¾ Cup of cornstarch
½ Cup of water
½ Cup of vegetable oil
Green food coloring (optional, other colors can be substituted)

This recipe will be runnier than the first. To start, mix several drops of food coloring and the water. Then pour in the oil and stir. The oil and water will not mix together completely.

Slowly add the cornstarch and mix well. More cornstarch can be added to thicken the slime. If you stop stirring, the ingredients will begin to separate. Stir them a bit and they will remix.

Materials:
Bowl
Spoon
½ Cup water
½ Cup glue
½ Cup liquid starch
Green food coloring (optional, other colors can be substituted)

This recipe looks more like snot that the previous two. Liquid starch is sometimes difficult to find in stores. See slime recipe 4 for a similar slime texture without the liquid starch. First mix the glue and the water in a bowl. The color and texture of the glue will determine how the snot looks. White glue will make the mixture thicker. Clear glue will look more translucent. Add food coloring and stir.

Then add the liquid starch. The mixture will begin to thicken and clump together. If you pick it up with the spoon or with your hand, it will ooze and run like snot.

Materials:
Bowl
Spoon
Cup
Water
Tablespoon of Borax powder
School glue
Green food coloring (optional, other colors can be substituted)

The texture of this recipe is similar to real snot. This is my preferred recipe for slime. Borax can be an eye irritant or can be harmful if swallowed, so monitor children carefully when making this recipe.

In a separate cup, mix a tablespoon full of borax and ¼ cup of warm water. In the bowl, mix half a cup of glue and half a cup of water. The exact measurements do not matter as much as making sure you have equal parts water and glue. Add several drops of food coloring to the glue and water and mix well.

Pour the borax mixture into the glue mixture and stir. The slime will immediately thicken and glob together. You can use the spoon or your hands to play with the slime. You can wear gloves if you are concerned about the Borax. If you want thicker slime, add a bit more glue until you get it to the desired consistency. Add more water for thinner, runnier slime.

There are two ways to make your slime glow in the dark. Either method will work with any of the slime recipes. The first way is to add glow in the dark paint or powder to the slime as you are mixing the ingredients.

The second way to make glowing slime is to substitute tonic water for the regular water in the recipes. Tonic water glows under a black light, so the slime will glow when tonic water is added.
