Materials Required:
l 2 cherry cough drops
l 2 small jars, such as baby food jars, with lids
l Water
Procedure:
- Place a cough drop in each small jar, then fill each about halfway full with water.
- Screw the lids on tightly. Gently shake 1 jar by turning it upside down and then right-side up, over and over again. Leave the other jar alone.
- After several minutes, notice the colour of the water in the 2 jars. The jar that you shook contains water of a deeper colour than the jar that remained quiet.
This Is What Happens:
When the jar is shaken, the motion of the water helps to dissolve the cough drop more quickly. When you eat, your stomach acts the same way. It does not sit still, but rather the muscles squeeze and churn the food so that it breaks apart into pieces and becomes watery.
