Next, pull apart and un-roll 4-5 galaxy jar cotton balls and place in the bottom of the mason jar. Sprinkle glitter on top.

Slowly pour the first paint colour over the cotton balls until they soak up the water.

If you accidentally add to much water, then just add a few more cotton pieces to soak it up.
