In a small bowl, mix your borax powder and 1 cup of warm water. Stir well until the borax powder is dissolved and set aside.

Evenly divide your clear glue into 2 separate bows (4 oz in each bowl).

Pour 1/2 cup of warm water into each of the bowls from step 2 (this is your remaining 1 cup of water). Stir well.

In one bowl, add the neon green and green food coloring and stir well.

In the other bowl, add the blue food coloring and stir well.

Next, take your borax mixture and slowly pour some into the green colored mixture. Stir well. Be careful to not pour too much or you will ruin your slime.

Repeat step 6 with the blue colored mixture.

Once your slime is made, add half blue slime and half green slime into each storage cup (put the green slime on the bottom and blue on top).
