My kids are obsessed with slime, so we tried something new and added sand to our slime for a whole new texture. We love this Monster Slime with little glow in the dark fangs and eyeballs that add just the right amount of spookiness. When left sitting the sand settles and the monster pieces raise to the top, in a swamp monster kind of way, that my kids think is awesome!

Add liquid starch in 1/4 cup increments to the glue/sand mixture until it stiffens. Stir well before adding more liquid starch. Slime will start to pull away from the sides of the container when the right consistency is reached.

When the slime has thickened, take it out of the container and work with your hands until it becomes stretchy. A small amount of contact solution can be added if the slime is too stiff.
