READ THE SAFETY NOTE BELOW BEFORE CONDUCTING THIS PRACTICAL
It can also be conducted as part of a simple investigation by varying the object placed in the lemonade and observing any differences in outcome.
Equipment typically required (per set)
Bubbles are formed at nucleation points on the rough surface of the nut for as long as there sufficient CO2 in the lemonade. Eventually the lemonade will go flat and the cycle of rising and falling will cease.
Conducting this experiment as a simple investigation may involve changing the type of drink used from lemonade to maybe soda water or cola and/or changing the object placed in it. Also students may want to measure how many times per minute the object rises and falls. This may relate to the amount of CO2 present as well as other factors.
