Now add enough cotton depending on the size and shape of your jar. Make sure to completely soak it in the dyed water and keep pressing down with your straw until the cotton fully submerged. Then add some glitter to the solution and shake it up so that the glitter spreads.
5The next step is a little different. First you are going to put more cotton on top of the first level, to create a second layer. Then make a solution of water and another color of dye in a separate container and pour that solution over the second layer of cotton. Then add more glitter and spread it around with a straw.
