Magic Milk Science Experiment

To set up the magic milk science experiment, you only need to grab a few supplies.

  • Milk
  • Liquid food colouring
  • Dish soap
  • Cotton swabs


  1. Pour a thin layer of milk in a shallow pan.

2. Have the kids add drops of food colouring all around in the milk.

A simple science experiment for kids.

3. Then the kids will pick up a cotton swab and dip it in the dish soap.

4. Then put the cotton swab in the milk – pressing it down in one spot and holding it there for about 15 seconds.

A colorful and exciting STEAM activity for young kids.


1.  Set a water bottle or pop bottle in the middle of a pan to catch the toothpaste.
2. Mix these in a separate container and swirl together for a minute.  The yeast will catalyze (or speed up) the reaction.

** 2 Tablespoons warm water
** 1 teaspoon yeast

3.  Mix these in your pop bottle:

** 1/2 cup 6% hydrogen peroxide
** 4-5 drops food colouring
** squirt of dish soap


4.  Pour the yeast mixture into the pop bottle…and be amazed!


Jello Slime

  • 1 cup of cornstarch
  • 1 3 oz pack of Jello mix – any brand or color will work great
  • 1/2 cup warm water

With just 3 simple ingredients, this comes together for a really fun slime activity everyone will love.

First, combine the cornstarch and jello powder mix in a large mixing bowl until they are well combined.

Jello Slime is so cool to make and you only need 3 ingredients. Make edible jello slime today for a super fun activity with the kids that is really simple.

Next, add in 1/4 of a cup of the warm water into the mixture and stir until it’s well combined.  It will be lumpy and difficult to stir once you add water. Don’t worry, just keep working with it.

After this, you’ll need to use your hands to mix in the last 1/4 cup of the warm water.  Knead the slime with your hands until the jello is the consistency that you prefer.

We like it to be firm if you squeeze and not drip like a liquid. Pull it slowly and see if it stretches if you pull.

Pull it apart fast and watch it stretch. So fun!

Tips for making jello play slime:

If your slime is too sticky, add more cornstarch.  If the slime is too firm, add more water.  You can easily work with this slime recipe until it’s perfect!
