DIY Experiments for Pre-K and K

Below you will find all the recipes and instructions for the DIY Experiments for Pre-K and Kindergarteners.

Please note, the only activity that is taste-safe is the Marshmallow Fluff Dough.

Marshmallow Fluff Slime


1 c Marshmallow fluff

3/4 c Cornstarch

1/4 c Powdered sugar

Mix the marshmallow, powdered sugar, and about half of the cornstarch together until well-blended. Add the rest of the cornstarch little by little until it reaches ideal dough consistency. It should be tacky to the touch, but not so sticky that it will not come off of your hands! This recipe keeps in an air-tight container in the fridge for 3-5 days.


Coat your hands with coconut oil before and during play to avoid getting too much of it stuck to your hands. If it becomes too dry, throw the dough in the microwave for 5-10 seconds and knead it again. While this recipe is edible, eating a while bunch may give your kids tummy aches.

Rainbow Rainclouds


Shaving cream Clear glass

Food coloring Dropper


Find a clear glass or plastic container, such as a drinking glass. Fill it 1/2 to 2/3 of the way with water. Top the water off with a good pile of shaving cream. In small containers, mix a few drops of food coloring with water. Using the dropper, kids can then suck up colored water and squeeze it onto the shaving cream. Watch as colors mix in the cream and eventually make their way through to the water, "raining" down below the shaving cream "clouds".


Use this opportunity to talk to your kids about color mixing! Start with the primary colors: red, blue, and yellow, and talk to them about what colors they notice after the colors start to mix.

Fake Snow


1 c Baking Soda Tray or container for snow

1 c Cornstarch *Optional: Glitter

Shaving cream

Start by pouring the dry ingredients into a medium container or tray, such as a baking tray. Spray about the same amount of shaving cream onto the soda mix and mix it in using hands or a spoon. Continue adding shaving cream until the mixture is slightly moldable, but not wet. Top with glitter and play!


Use dough tools or other kitchen utensils to play in the snow. You can even put the shaving cream container in the fridge for a half hour or so before making the snow to make it realistically cold!

If adding glitter, scrape the mixture into the trash after playing. Otherwise, it should be fine rinsed into the sink without a problem.
