How to Store Slime Recipe

Slime is a ton of fun to make but it does not last forever, The longer slime is exposed to air and left out in the open the quicker it will go bad. It is important to store your homemade slime if you want to keep it stretch and fun to play with so you can use it again the next day.

Not every slime recipe can be saved to platy with again later, some recipes go bad much quicker than others and some like Magnetic Slime will start to rust. Here are our eight favorite ways to save your slime so you don’t have to make another batch!

1. Ziplock Baggies

Plastic zip lock bags are the most popular way to store slime. They are convenient – most people already have a box on the kitchen, easy to use – all you need to do is insert slime and seal the bag and they are cheap – a big box of bags cost a few dollars.

A well sealed bag should keep your slime fresh for a few days but don’t expect much longer. Plastic bags are porous which means small amounts of air move and out through the side of the bags. Plus you will never be able to remove all of the air from inside the bag no matter how hard you squeeze.

2. Tupperware Containers

Tupperware containers are another easy way to store slime, and they are reusable so you are not adding more trash to the landfill. Most people have extra Tupperware for saving leftover food so you won’t even need to go to the store.

Put your slime inside a clean plastic container and seal the lid tight. In our experience sandwich size containers are the best size for most recipes. It can be kept out of the sun or inside the refrigerator for best results. Make sure to clean it in a few days or it might ruin the container.

3. Inside the Refrigerator

Storing your slime inside the refrigerator is the best way to extend its life. Even if you keep it in an airtight container it won’t last long at room temperature. In our experience the best way to store slime is in an airtight container that is placed inside your fridge – just make sure it does not get eaten!

Keeping your slime cool can keep it fresh for up to a week for some recipes and up to a month if kept inside an airtight container. Just make sure to seal the lid tightly and get as much air out as possible to keep it from drying out.

4. Inside the Freezer

Some recipes like, Edible Slime, save better inside the freezer. These recipes tend to be firmer and do better in the freezing temperatures. It may take a few minutes for them to defrost before you can play with them so make sure to plan ahead. You should also keep them inside the Ziploc bag or plastic Tupperware container.

It will take a few minutes for the slime to defrost before you can play with it but once it is ready it will be super cold – perfect for summer fun!

5. Inside a Vacuum Sealed Container

The most common reason slime dries out or gets moldy is contact with air. If you want to store a batch of slime for a long time (longer than a month) we recommend using a vacuum sealed bag or container. Vacuum sealing removes all the air from inside the container, leaving only your slime.

The will preserve it for a few months if kept inside a refrigerator. Try not to open the container to “check” on your slime, every time you open it up more air will get inside.

Mason jars are a good way to store slime for long term use. The glass sides are don’t let any air inside and the top seals airtight. The only downside is not everyone has empty mason jars at home.

You can save food jars from things like pickles or buy a few from the store, they are super cheap! Remember, mason jars are made from glass so don’t let little kids break the jar and hurt themselves.

8. Inside Baby Food Jars

Baby food jars are a creative way to store small amounts of slime. These small jars are similar to mason jars and can store slime for a long time inside the refrigerator. The only problem is that only families with small children will have them at home – or you can buy them by the dozen at an arts and crafts store.

Baby food jars are both good and bad. On one hand they are small and can only save a small amount of slime and breakable. On the other hand they can keep slime safe in an airtight container and don’t take up much room in the fridge, plus if your family has a baby you can recycle jars.
