Very cool project!
I wonder how it would be different if you did a “party” test. Place 12 beers in each cooler, then open and close each cooler once every 1-5 minutes, and see which keeps the beer the coldest at “initial cooler open”.
I realize this might need a mechanical arm or something, but it’ll obviously be worth it.
Thanks, I think that’s a great idea! The results from this project are what they are because the coolers were sealed pretty tight. My first hunch is with a lot of air exchange the dry ice will disappear pretty quickly. I’m going to figure out a way to try this!
His conclusions about dry ice don’t surprise me personally, but a neat write up nonetheless.
Thanks! I wasn’t surprised by much either was pretty curious. I’m going to try some variations on the project just to goof around.
I’d be curious to see the graphs if you were actually trying to cool something: like half-fill the cooler with room-temperature bottles of water or cans of soda/beer. Then add (wet/dry) ice, and see what happens.
