SUGAR RAINBOW

In sugar rainbow experiment we want our students realize that olored sugar, solutions, made at different concentrations can’t be mixed. The solutions form layers, from least dense, on top, to most dense (concentrated) at the bottom of the glass.

What You Need:
1.  sugar
2.  water
3.  food colouring
4.  tablespoon
5.  6 glasses
6.  measuring cylinder 100 ml
7. syringates 50 ml

Here's How:
Line up six glasses. Add 10g of sugar to the first glass,  20g of sugar to thesecond glass, 30g
to the third glass, 4 g to the fourth glass and 50g to the fifth glass. The sixth glass remains empty 
Add water to each glass until 100g. Stir each solution.
Now we colour the sugar solutions using food colouring

0% w/w
red
10% w/w
orange
20% w/w
yellow
30% w/w
green
40% w/w
blue
50% w/w
Dark blue

Now let's make a rainbow using the different density solutions. Fill measuring cylinder with 20 ml dark blue sugar solution.
Carefully layer 20 ml blue sugar solution above the dark blue liquid
using the syringates.
Now layer 20 ml green solution above the  blue liquid and continue with yellow and orange solution.

Finally, layer the red solution above the orange liquid.
