Boredom, You’ve Been Slimed: Easy Slime Recipe

Our pink and blue neon food coloring made pretty lavender cornstarch slime. Yes, I called slime pretty.

It seems like once we pass July 4th that the rest of summer flies by at supersonic speed. Unfortunately my girls then slip into SBT (Standard Boredom Time).

My 7-year-old loves to cook and loves experiments so I surprised her during a torturous trip to the grocery store (oh the cruelty!) and told her we were going to pick up ingredients to make homemade slime and flubber.

Easy Homemade Slime Recipe

2 parts cornstarch
1 part water
Food coloring (we chose fun 80’s neon colors)

Mix in a large bowl, using your hands. Don’t add too much water. Slime should not be runny but can be made to whatever consistency you like best. Use food coloring. If your slime gets too hard, a small amount of water can be added.

Our snot green Flubber. This stuff looks like something Shrek hacked up and feel like it, too.

Metamucil Flubber

1 tsp Metamucil (I used generic Kroger brand) or similar soluble fiber
8 oz water
Food coloring

Mix 1 teaspoon of Metamucil with 1 cup (8 ounces) of water in a microwaveable bowl. You can add a drop or two of food coloring if you wish. Alternatively, you could add a little powdered drink mix or flavored gelatin to get color/flavor. We used neon green food coloring.

Place bowl in the microwave and microwave on high for 4-5 minutes (actual time depends on microwave power) or until the goo is about to bubble out of the bowl.

Let the mixture cool slightly, then repeat step 3 (microwave until about to overflow). The more times this step is repeated the more rubbery the substance will become.

After 5-6 microwave runs, (carefully – hot hot HOT) pour the flubber onto a plate or cookie sheet. A spoon can be used to spread it out.

Allow to cool.A knife or cookie cutters may be used to cut the flubber into interesting shapes. Flubber can be stored at room temperature in a sealed baggie for several months. It will last indefinitely in a sealed bag in the refrigerator.


If the flubber is sticky then the amount of water needs to be reduced. It should be clammy, but not sticky. Use less water next time.

So there you have it. The next time your kids start whining about being bored, break out these slime or flubber recipes. We played “spa” with our concoctions and I have to say that the snotty green flubber we made definitely gets the GROSSEST award. It would be great to make this Halloween.

    I’m excited – and afraid – to try these with my kids. I’m also a little nervous for the dog. :-/

    Thanks for posting!
