First Year Carbon dioxide experiment.

Here is a video taken with my first year class when we demonstrated that carbon dioxide gas is heavier than air.
We put two plastic bags at the end of a long piece of wood.
Then we balanced the beam of wood and poured out the invisible gas made by adding vinegar and baking soda.
Later we tested the gas with lime water. The gas turned the lime water milky. This test told us the gas was carbon dioxide.
Well done 1/7.
