Q&A for How to Store Slime

As long as it is stored in an airtight container, it should last for a few weeks to a few months.

Yes. The best way to store slime is by putting it in an airtight container. It is not mandatory to refrigerate if you put in an airtight container.

Proper storage will go a long way, but you should also pay attention to the ingredients. Consider a recipe that uses liquid starch instead of Borax. Slime made from liquid starch wil last much longer than slime made from Borax.

It is most likely drying out. Try adding a little lotion every time it gets hard. Work it in with your hands and it will freshen the slime. Also, keep it out of the sun and in an airtight container.

Various stores have airtight containers in stock and a simple search can help you find locations in your area. Some stores that carry the product include Walmart, Amazon, Target, etc.

That means that the container isn't air-tight. Look for one that is marked as air-tight. Also, no slime will last forever and it will dry out/need to be thrown out eventually.

Add lotion. Lotion can help it become softer and stretchier.

Try to add activator, like Borax. If this doesn't help, maybe it`s getting old and you might have to throw it out.

Try to store your slime into an air-tight container. Or, you can put the bag inside another bag or box.

Add some activator. Use borax, liquid starch, or contact lenses solution (add baking soda to if it is not fluffy slime) or shaving cream.
