I was thinking on those high school experiments about density and such where you take some vinegar and baking soda in a pitcher, then snuff out some candles by pouring the CO2 over them or make a balance fall to one side etc.

For those who don't have a lot of money to vacuum seal or don't buy enough at one time to justify buying a bunch of those oxygen absorbtion packets; is CO2 dense enough to displace enough oxygen in say, a bucket of rice?

as was mentioned in another post, if you can inject the CO2 low in an airtight container, leaving the top open it will displace oxygen. you'd want to calculate the right volume with canisters, dry ice or catalyzed CO2 before trying it though.
