How to make slime with contact lens solution

There are several ways to make homemade slime - but the most popular is the method that uses contact lens solution. Why? Because contact lens solution usually includes boric acid, this is what adds that satisfying stretchy and squishy texture. So when choosing a contact lens solution for slime, ensure you pick a product including boric acid.

Here are the ingredients to make homemade slime:

1. 120ml of PVA glue (½ cup)
2. ½ Tbsp of bicarbonate of soda
3. ½ cup of shaving cream (not gel)
4. 1 Tbsp of contact lens solution (remember, one with boric acid, like Renu MPS)
5. Food colouring (optional if you want to make coloured slime)
6. Glitter (optional if you want to make it shine!)

1. Use a big bowl to mix all ingredients thoroughly
2. Pour the 120ml of glue in the container. Add 2 Tbsp of water and stir with a spoon or spatula
3. Add the shaving cream and stir again
4. Add the bicarbonate of soda and stir
5. Add the food colouring and glitter. You can add them gradually and stir several times until you get the desired consistency
6. Now add the contact lens solution. Add slowly whilst you continue to stir. Check the consistency, too much and the slime won't be elastic
7. As the slime becomes less liquid, take it out of the bowl and knead it with your hands. If you feel it still sticks too much to your hands, add a bit more of solution.
8. Knead, knead, knead… TIME TO PLAY!

Your slime with contact lens solution is ready! Feel free to experiment with different amounts for different textures: for example, adding less shaving cream so the result is less fluffy, adding different or multiple colours, tweaking the amount of solution…the world is your slime oyster!
