Whisk the ingredients together in a medium microwave safe bowl until smooth. Cook in the microwave on high for 5 minutes and then whisk again. It will still be runny so you'll want to keep cooking 4-5 minutes at a time until the mixture becomes the texture you like your slime. Let it cool completely before playing with it. Add it to condiment cups for an easy party favor! Enjoy under a blacklight and watch it glow!
