Due to weather and shipping conditions, slimes may arrive sticky, stiff, or completely melted or frozen. To fix sticky slime, add the 1 teaspoon of powdered borax provided with your order to 1 cup of hot water and stir until it is fully dissolved. Then, slowly add a few drops to the slime and knead it in. Repeat this process until the slime is no longer sticky, but BEWARE that it is easy to accidentally over activate the slime which would make it stiff. To fix stiff or frozen slime, try leaving it in a sunny area for a few hours or a day. If this doesn't work, you can slowly add warm water or unscented lotion or vegetable glycerin to the slime.
