Questions To Ask Your Kids

What does the snow feel like?
Is it cold like real snow?
Can you build a snowman?

Kids can have great fun building their own snowman. They can use a cocktail stick to make a nose and a ribbon as a scarf. We cut a small part off the cocktail stick and painted it orange. Use small sticks or twigs for the hands and arms. For the eyes and buttons use small stones or beads. 

The Science Behind The Experiment

Mixing  together the  bicarbonate of soda, a  solid with hair conditioner, a liquid, creates a matter called a colloid.

What Is A Colloid?

A colloid is a mixture of two or more substances mixed together but not chemically combined.  Combination of molecules mixed through other substances that will not settle out or join with the other substance. 

This colloid feels like snow and it is cold to the touch.  Bicarbonate of soda (sodium bicarbonate) mixed with the hair conditioner (lanoline) creates a mixture that is cold to touch, otherwise known as an endothermic reaction

What Is An Endothermic Reaction?

An endothermic reaction occurs when energy is taken in from the surroundings and the temperature of the surroundings decreases.

 It is fairly rare to get an endothermic reaction in the safety of your own home without using actual chemicals.
