Why do the colours spread? Skittles are coated in food colouring and sugar. When you pour water over the skittles the
coloured coating dissolves spreading through the water
. The colour and sugar dissolve into the water and then diffuse through the water, making it the colour of the skittle.
What is the purpose of the skittle experiment?
This science experiment covers
a fundamental part of chemistry – chemicals move from higher concentrations to lower concentrations
. This is called a concentration gradient and can be found in everything from perfume vapors wafting through the room to cordial spreading out in water.
Why do the Colours not mix in the Skittles experiment?
The coating on a skittle is made up mostly of sugar and food colouring. The warm water causes the colouring and sugar to dissolve and diffuse through the water. The reason the colours do not initially mix is
due to water stratification
. … This creates a barrier that prevents the colours from mixing.
Why do Skittles dissolve in water science fair project?

What happens when you add hot water to Skittles?
Skittles are coated in food colouring and sugar. When you pour water over the skittles
the coloured coating dissolves spreading through the water

more active in warm water than
in cold water and as they come in contact with the sugar in the skittles they cause it to dissolve faster.
Which liquid dissolves M&Ms the fastest?
EXPLANATION: The
water
did the best job of dissolving the coating on the M&M. Second best was the alcohol, and the oil did not dissolve the coating at all. The candy coating on the M&M's contains molecules that have one positively charged end and one negatively charged end.
