Can you imagine that candy will transform a rainbow? It is cool, right? Here, our Pandai Lab 2 brings you to transform Skittles into a rainbow within seconds by the power of dissolving!
On 19 October 2020, Monday, we make a rainbow using Skittles candy. This colourful science experiment is as easy as 1-2-3 and will keep them amused for as long as you can spare more Skittles.
Here the details:
Date: 19 October 2020
Title: Rainbow Experiment
Materials: Skittles candy, white plate & a glass of water
1.Arrange the Skittles in a single row coloured pattern around the edge of the plate.
2. Pour over enough water on the center to cover all the Skittles and the plate itself.
3. The colours will move towards the middle and create a whirl of colour.
4. Watch and wait as a rainbow appears on the plate.
What makes this possible and happened?
Candy is full of dye (usually), which means the combination of dye and sugar dissolves quickly in water. Skittles are particularly good for this experiment because they are colorful and dissolve even faster than other candies. When you add warm water to the Skittles, the sugar and food coloring start to dissolve. They have similar amounts coated on them so they dissolve at similar speeds and stay in their lanes. The sugar is moving to areas of water with lower sugar concentration. If the water is poured in the center, this is happening for each Skittle at relatively the same speed.
