Question: how to make your slime not sticky without borax?
Answer: Mix 1 tsp (4 g) of baking soda and 1 tbsp (15 mL) of water in a cup. The exact amounts do not matter; you want a solution that looks like cloudy water. If the solution is so thick that your spoon leaves streaks in it, add more water. Add the baking soda solution to the slime until it is no longer sticky.
