How to save and store your Wonder Slime:
First rule of keeping your Slime wonderful is to make sure you put it back in its container when you’re not playing with it. This is because the slime contains air drying ingredients so the more time it spends out, the quicker it will dry. Only keep your Slime in the fridge if it had gone a bit too slimy from playing with wet hands or if it melted in the sun.
Here are some things you can try to get your Slime back to its Wonder state:
Use warm water
One of the easiest ways to transform hard and brittle slime is to use warm water. Add two tablespoons of water to your slime in a microwave safe bowl. Microwave for 5-10 seconds, then knead the water into the softened slime. It absorbs the water, re-hydrating it immediately. Discard any leftover water.
