Science is awesome! Simple science experiments that are mesmerizing are even better!
We have played with oil and water tons of times over the years with our kids. Just recently however we discovered the joy of emulsion agents! If you haven’t played with oil and emulsions – try it.
You’ll need some kids, this science experiment is a favorite! Had my kids playing all day.
Science Ingredient List:
- Food Coloring
- Vegetable Oil
- Egg Yolk
A simple science experiment:
Pour oil into a plate enough to completely cover the bottom of the dish. Mix up the water and the food coloring. Then pour your dyed water into the oil. So cool to watch the globs moving in the dish.
Have your kids stir the oil and water, trying to mix them. Then sit and watch as the water separates from the oil again.
Next, stir up your egg yolk and drop a couple of spoonfuls of yolk into the oil and water. Mix the water and oil again. When you stir it the liquid will become creamy looking as the two liquids mix. Chemistry!
This is exactly why so many recipes you make require eggs. Egg yolk has something called lethicin in it that helps oil and water to connect both to each other and to the other ingredients in your recipe.
