• The amount of dish soap you use is not certain. Add a little bit at a time until the texture is right. It should look like a green pudding.

Add baking soda if the mixture is still thin. If you accidentally add too much dish soap, the slime will be a bit thin. If the slime looks thin like water, add baking soda to help alleviate the problem.

Add some food coloring if needed. If the slime isn't the dark green you want, add a few drops of food coloring. This will give the slime a darker green color.

Measure the vinegar in the bowl. Place 2 cups of white vinegar in a bowl. You only use white vinegar. Don't replace it with something else like apple cider vinegar.

Add xanthan gum. Xanthan gum is a thickening and stabilizing agent. You can buy it online or at a cosmetic ingredient store. Put 1 and 1/4 teaspoon of xanthan gum in a bowl with vinegar and stir well. Continue stirring until the white molecules are gone and the mixture is smooth and transparent.

• Xanthan gum is sometimes difficult to find at supermarkets. You must order online, so be sure to order a few days before you want to make a slime.

Add green food coloring. A few drops of green food coloring will make the mixture look softer. You should only add a few drops first and increase gradually until the mixture is the color you want.

Stir the slime one more time. When you take the mixture out of the refrigerator, stir it once more. Keep stirring until the slime looks cloudy and slightly creamy.

Add vinegar until texture is correct. To check that the mixture is ready, scoop out some of the mixture with a spoon and pour it back into the bowl. The mixture flows quickly down the bowl. If it's too thick and flowing slowly, add a little vinegar and stir.Keep adding the vinegar until the mixture drips down easily.

Pour the mixture on a surface covered with baking soda. Once the slime has thickened, pour it over the baking soda surface. Baking soda is alkaline and slime is acidic because of the vinegar. Adding baking soda will make the slime bubbly. The more baking soda you add, the stronger and longer the slime will foam.

Play the slime. There are many ways to play with slime. You can imagine slime as poisonous water on a certain planet for example and play with a toy astronaut. Alternatively, you could also use toy dinosaurs and imagine the slime as some prehistoric slime. Some people just need to watch the effervescent slime.

• Remember to wash all toys after playing with slime.
• Don't eat slime because it's not safe to swallow.

Method 3 of 3: Make the polymer slime

1. 

   Put the milk in the cup. You will need 7 tablespoons of nonfat or skim milk in a cup or bowl. The fat in whole milk won't create the correct texture, so don't replace it with whole milk or 2% fat instead of skim milk.

2. 

   Add more vinegar. Stir 1 tablespoon of vinegar into the milk. This amount of vinegar is enough to separate the protein in the milk. Adding vinegar increases the acidity of the milk and separates the protein.
   • You will see small lumps in the milk as the milk reacts with the vinegar. These blocks will slowly sink to the bottom of the cup as the reaction occurs.

3. 

   Filter the mixture with coffee filter paper. When the milk blocks sink to the bottom of the cup, pour the liquid into the coffee filter paper. The liquid will flow to the filter paper and leave only the milk mass. Pat the cubes with a paper towel to make sure they are dry and drained. Then, put the block of milk in the bowl.

4. 

   Mix in baking soda. After filling the bowl, add ¼ teaspoon of baking soda. Baking soda will help the protein coagulate and have a firmer texture. The mixture will gradually form a slime. Add baking soda until you have a texture similar to the pudding texture.
   • Depending on the size of the block, you will add baking soda. If you are having trouble making the pudding mix, sprinkle a little baking soda each time until you get the texture right.

5. 

   Add green food coloring. A few drops of green food coloring will give the slime its color. Add color and stir well. If you want dark green, add more food coloring.

6. 

   Play the slime. Once you're done with the slime, you can play with it right away. Shape the slime by hand. Or you can also use it to decorate the pattern. For example, using slime to make mud in the forest.
   • Note not for slime and mouth. It is not safe to eat.
