Easy Flubber Slime
Flubber slime is a very thick and flexible material. You may build a far more robust slime by making a few tweaks to our original recipe. It hasn’t stopped dripping!

Flubber Slime Ingredients
- 2 bottles Elmer’s Non-Toxic Washable Glue White for a total of 1 cup
- 1/2 Cup Water
- 1/2 Cup Liquid Starch
- Glitter or food coloring optional
How to Make Flubber Slime
- In a jar, combine glue and water. Stir until everything is well blended and the consistency is smooth. It’s the ideal opportunity to add some color or glitter.
2. The liquid starch should next be added to the glue/water mixture. Begin by stirring with a spoon.
3. To thoroughly incorporate the ingredients, switch to using your hands. Continue combining and kneading the flubber for a few minutes.
You can play with your flubber right now or wait around 15 minutes for it to set up.
Unless you have a lot of hands playing with it, store your flubber in a jar with a lid for several weeks.
Flubber Slime Interesting Facts
1. Flubber is used in several world records. A twelve-year-old holds the Guinness World Record for the world’s largest flubber, weighing six tons! The record for the longest flubber is held by a ten-year-old who stretched to 7 feet 4 inches in 30 seconds.
2. Adding shaving cream to flubber slime can make it even puffier and fluffier!
3. Mattel, a toy business, created Flubber in 1976. Green was the first color!
4. Flubber is a Non-Newtonian fluid, which means that it is neither solid nor liquid. Other toys that fall into this category include playdough and silly putty.
5. The ooey gooey texture is achieved by combining Borax and glue, which makes a polymer (when several small molecules are formed into one large molecule).
6. Take care! Vinegar can be used to dissolve flubber.
How to Keep Slime Safe
Making your own slime is a fun afternoon hobby for the whole family. It may be made with minimal components and then played with for hours. Of course, you’ll want to keep it fresh once you’ve made it, and the easiest way to do so is to store it in an airtight container in the fridge. When it starts to go bad, chuck it in the garbage.
Using a Ziplock Bag
- Place the slime in a plastic bag and seal it. For storage, a simple ziplock bag from the kitchen would work. Choose a container that is just big enough to hold your slime. You don’t want one that’s too big because you want the bag to be as airtight as possible.
- Squeeze the air out. Partially zip the bag and then press out as much air as possible. Your slime will dry out if exposed to air, so getting it out will help preserve it.
- Close the bag. Zip the bag up securely once you’ve gotten as much air out as you can. Check to see if the zipper is completely closed. Remember that the slime may adhere to the bag.
- Place the bag in the fridge to chill. The slime will last longer if the bag is kept in the refrigerator. The slime can grow germs and/or mold, which will make it smell bad, although the refrigerator can help slow this down.[2] However, some slimes will harden when refrigerated.
Slime Preservation in an Airtight Container
- Choose a jar that is just big enough to fit your slime in. Air is your adversary since you don’t want your slime to dry out. Choose a jar that will only hold your slime. To avoid the slime from drying out, tuck some plastic wrap on top of it. Cover the slime with plastic wrap.
A plastic food storage container will suffice.
- Close the container tightly. Close the container carefully, making sure it is completely sealed. A screw-top container or jar can also be used. You want to keep as much air out as possible!
- Place the slime in the fridge. The refrigerator is the greatest location to store slime. Bacteria, mold, and other icky stuff will be slowed down by the cold.
Maintaining the Freshness of Your Slime
- Avoid getting slime on filthy surfaces. You’ll have to dump your slime if it settles somewhere disgusting, like in the soil. To help maintain it, it’s preferable to keep it away from these regions.
- Before you play with your slime, wash your hands. Bacteria on your hands can make it easier for dangerous bacteria to develop on your slime. Before you play with your slime, make sure you wash your hands properly. Scrub for at least 20 seconds with soap and warm water. Scrub for 5-10 seconds if your slime is a softer watery slime, else it will become runny and too sticky to touch. You can also soak your nasty slime for 10 minutes in warm water (not hot or it could melt your slime).
- Fill the dried slime with water. You can put your slime in a bowl and add extra water if it has dried out. With your hands, combine it until it softens. You can also replace the water with a drop or two of antibacterial gel.
Slime Elimination
- Before the week is up, check on the slime. Your slime won’t survive long, typically a week or less. Play with it before it goes bad, and check on it again in a week to see if it has.
- Remove any rotten slime. It’s time to throw out your slime if it starts to sprout anything. Mold can cause white or blue fuzz to grow on top of it. If you notice it, take it as a cue to make some new slime.
- Search for filth. It’s time to dump your slime if it starts to look nasty. You might notice that it’s a different hue or smells strange. If you drop it somewhere disgusting, it’s also time to throw it.
- Place the slime in the trash. Because slime appears liquidy, you might be tempted to flush it down the sink. It is, however, far better to throw it out because it can clog the drain.
