HOUSTON (KIAH) – They may be small but they are intense! Especially when it arrives to STEM things to do and schooling. We’re speaking about 2-yr-outdated Krissy Lister and her 1 yr-aged sister, Kinsley Lister.

Their mom Crystal Lister has commenced a YouTube channel, Mommy and Me: The Listers. Its an interactive and academic avenue the place Crystal shares her passion and expertise for instructing STEM instruction by means of her two little co-stars. 

They join Houston Occurs host Maggie Flecknoe to share three of their favourite experiments. You can participate at house! See underneath for additional on each and every experiment. 

Experiment #1

“The Magic Milk” for ages 3 and up


  • Plate
  • Q-Suggestion
  • 2-ounce cup
  • Milk
  • Dish Cleaning soap
  • Food stuff coloring


  1. Pour the milk on the plate
  2. Add drops of meals coloring to the milk in the plate, be guaranteed to area the drops out
  3. Dip the Q-idea in the cup with the dish soap then
  4. Dip the Q-tip with cleaning soap on it in the plate with the milk and the foodstuff coloring and view magic transpire!

Science at the rear of it:

The body fat in the milk reacts with the dish cleaning soap creating the molecules to transfer close to. This is why complete milk will respond greater than a small extra fat, or a 2% milk would.

Experiment #2 –

“Elephant Toothpaste” or that we renamed Elephant Soap for ages 3 and up*

Grownup supervision essential


  • Protection Equipment (gloves, goggles, apron or lab coat)
  • 3% hydrogen peroxide or 30% Hydrogen Peroxide for the major response (grownup supervision with managing expected)
  • 1 packet of Active Yeast or 1 spoonful of Potassium Iodide for most significant reaction
  • Foodstuff Coloring
  • Erlenmeyer flask
  • Beaker
  • Stirrer
  • Measuring Cup
  • Drinking water


In this video, we are legitimate experts and carry out the experiment with diverse components to see which will make the most significant and foamiest Elephant Cleaning soap! We substitute the yeast with potassium iodide and 3% hydrogen peroxide with 35% hydrogen peroxide for a even bigger response but, be careful and request an adult before use or managing.


  1. Pour half a cup of 30% hydrogen peroxide in flask
  2. Increase a couple of drops of foods coloring and a squirt of dish soap to the peroxide in the flask
  3. In a independent beaker mix a spoonful of potassium oxide into 2 tablespoons of water
  4. Stir right until crystals have dissolved building a remedy
  5. Pour Potassium Oxide solution into the flask with the peroxide
  6. Action Back again
  7. Enjoy the chemical reaction produce the Elephant Cleaning soap

Science at the rear of it:

In this exciting foamy experiment, it demonstrates a chemical response the place the foam is oxygen-filled bubbles that consequence from the hydrogen peroxide being damaged down into drinking water and oxygen. This reaction makes use of either yeast or potassium oxide as a catalyst to pace up the response.

Experiment #3

“Sink or Float” or Relative Density for ages 3 and up*



  1. Fill your bin up with drinking water
  2. Throw items in the bin of water
  3. Observe if it will sink or float

Science at the rear of it:

In this soaked experiment, Krissy and Kinsley take a look at out unique residence objects to see if they are much more dense and will sink or considerably less dense and will float in water.
