Carbon Dioxide Experiment

Is there any experiment that I can do with carbon monoxide
Carbon monoxide has very rich chemistry. However, I can not recommend
working with CO, because it is extremely toxic, colorless, and odorless.
In other words, you can be poisoned before you know it. Experiments with
carbon monoxide are performed in special laboratories with controlled
ventilation and dedicated carbon dioxide detectors, and only specially
trained people are allowed to do the work.

I don't think you should do any experiments with carbon monoxide.
It is a very dangerous gas. If you breathe it you may die.
You can do some experiments with carbon dioxide instead. Carbon
dioxide is harmless. You can breathe as much of it as you want.
Here's an experiment you can do: get three balloons. Fill one of them
up with air, one of them up with helium, and one of them up with
carbon dioxide. Compare the weights of the balloons. The helium
balloon will be so light it will float in air. The carbon dioxide
balloon should be heavier than the air balloon. This will let you
talk about the different densities of the 3 gases, and how the density
determines whether the balloon will float or sink in air.
You can get helium for your balloon from a flower shop. Carbon
dioxide will be harder, perhaps it would be best to get some dry ice,
put it in a small plastic container with a thin tube leading out of
it, let the dry ice evaporate for a while to chase the air out of the
container, then collect the gas in a big bag, and finally use the bag
to inflate your balloon.
