Add the white glue, baking soda, and water to a large mixing bowl. Stir well.
Add a few small squeezes of acrylic paint – about 1 teaspoon worth. The more you add the darker your slime will be.Keep in mind that when you add the shaving cream, the colour will lighten up quite a bit. So make sure at this point that the colour of your mixture is darker than what you want it to be in the end.
Step 3: Add the shaving cream
Next you can add the shaving cream. If you want, you can measure it into a measuring cup. Or you can spray it directly into the bowl and estimate the measurement. This recipe is pretty forgiving if you add too much or too little.I used about 3 cups of shaving cream in the fluffy slime you see in this tutorial.
Stir well until everything is combined. The mixture should be smooth, puffy and the colour should be consistent. It looks a little bit like whipped cream at this point.
Step 4: Add the contact lens solution
Now you can add the activator. Pour 2 Tablespoons of contact solution into to the glue mixture, and stir. As you stir, it will start firming up and getting stringy. Keep stirring until it has a good slime consistency and it stops sticking to the side of the bowl.If it gets too hard to mix with a spoon, feel free to use your hands to knead the mixture.If the slime is still sticking to your hands, add a little bit more contact lens solution into the mixture.That’s all there is to it!
