Using Edible Slime as Your Science Fair Project

I’ve got a whole write-up on using slime as a science fair project here if you want to take a look. It’s a very detailed look at how to take what at first glance is merely a preschool and Kindergarten friendly sensory activity and turn it into a full-on educational adventure.

It’s easy to turn edible slime into a science fair project. All you need to do is implement the scientific method.

Using these free scientific method worksheets, come up with something you want to test out – a question you want to answer or a problem you want to solve. Then, using the edible slime recipes below, begin testing out your hypothesis or theory and find the answer to your question.

How To Make Edible Slime

There are SO MANY edible slime recipes on the internet today. You can make slime out of marshmallows, starbursts, candy corn, sweetened condensed milk, Jell-O, and so much more!

Edible Marshmallow Slime

You will need:

• 1 cup of marshmallows
• ¾ cup cornstarch
• ¼ cup powdered sugar
• Coconut oil
• Food coloring if desired

Steps:

• Place your marshmallows in a microwave-safe bowl.
• Microwave for about 30 seconds then take out the melted marshmallows and stir.
• Add ¼ cup powdered sugar, and ¼ cup corn starch and mix until combined.
• Add remaining cornstarch little by little.
• Coat hands with coconut oil to prevent slime from sticking to hands or at least minimize the sticking.
• If it is too sticky add more cornstarch.
• It can be kept for a few days if it makes it past day one and microwave for 10 seconds to become pliable.

And voila! Easy peasy edible marshmallow slime. This recipe may not taste absolutely wonderful with the added cornstarch but it is completely safe if your kids do want to eat it. Or they can just enjoy the feeling of stretching and squeezing the slime between their fingers.

NOTE – DO NOT try this recipe with marshmallow fluff. Using marshmallow fluff resulted in a completely failed experiment that we do not recommend. Stick to regular marshmallows. (Unless, of course, you want to perform this experiment to have your kids try and figure out why one works and the other does not? That would make a fun scientific method application.)

Edible Candy Corn Slime Recipe

You will need:

• 1 cup candy corn
• 1 ½ cup marshmallows
• 1-2 tablespoons vegetable oil
• 1 cup powdered sugar

Steps:

• Take candy corn and cut off white and yellow ends and place in a bowl. Place orange parts in a separate bowl.
• Cut up enough of each to fill 1 cup of yellow and white pieces and 1 cup of orange.
• Use 1 cup of orange candy corn, 1 ½ cup of marshmallows, and 1 tbsp of oil to a microwavable bowl. Microwave for 30 seconds. Take out, stir, and microwave for another 15 seconds. You want there to be no clumps so continue to stir and microwave until it is smooth.
• Repeat step 3 with yellow and white candy corn pieces.
• Be careful with the mixtures because they are hot. 
• Now add ½ cup of powdered sugar to each bowl (½ cup to orange and ½ cup to yellow/white). Stir until it starts to thicken. 
• Then put each mixture on a cutting board to cool. This could take about 10 minutes. The candy corn mixture really holds heat so please be careful with little ones.
• Once cool, knead until it’s no longer sticky. Add a little more powdered sugar if needed.
• If you want you can take the two colors and twist them together and stretch!
• Store in a baggie in the fridge for a few days. Reheat for 25 seconds to soften.

The Science Behind Edible Slime

There is so much science behind edible slime. First and foremost, there is the concept of Non-Newtonian fluids when making slime. Non-Newtonian fluids are, in short, a substance that is both (or neither) a solid and a liquid.

It is worth noting that there are several ‘versions’ of slime and each has its own unique consistency. Play-dough slime vs Oobleck or Non-Newtonian fluids.

You’ll be adding molecules of different sizes in between your other larger (or smaller) molecules, which results in a Non-Newtonian fluid. This combination of molecules prevents the substance from solidifying and keeps it soft and pliable without actually becoming a solid.

The specific sciences involved will be determined by the specific recipe (or recipes) you use. But that is the science of making slime in a nutshell.
