Question: how to make edible slime not sticky?
Answer: The slime is a bit tacky, so if that bothers you, have some extra cornstarch or oil on hand to coat your hands with. The more you play with any edible slime, the stickier it can get so you may need to add more cornstarch/icing sugar to the slime if you find that it's getting sticky (and not just a bit tacky).
