  4. Slowly add in your contact lens solution
  5. Now mix until your slime forms and begins to harden.

Directions

The primary ingredient in our slime slime recipes was white glue. When you mix glue with other ingredients, the molecules become entangled, creating a slimy texture.

What Happened?

Baking soda (sodium bicarbonate) when combined with contact lens solution contains boric acid,which makes the slime more elastic and less sticky.

What Happened?

Contact lens solution contains acid reacts with the baking soda that gives the slime its unique texture.

What Happened?

The water helps with finding the right balance between stickiness and elasticity.
