You would have to leave the lid cracked or it will blow the lid off. We have used water and dry ice in gator aid jugs to remove small stumps. Kinda of sketchy and sensitive stuff.

Its getting hard to find Dry ice now days

AND, You can't live long in a CO2 atmosphere, make sure it's well ventilated. The term Dry Ice" comes from the fact taht most liquids will go thru 3 stages: Solid, Liquid, Gas; and Dry ice doesn't have a Liquid stage.

Yep..So I took off with 80 lbs of cubed ice and 10 lbs of dry ice..I loaded the cooler on Tuesday afternoon..I get to the location on Wednesday afternoon and take a peek in the cooler.."NO DRY ICE"..however the cubed ice was frozen..SO..I went to the store that had it..I walk in with a pair of heavy leather welding gloves and asked for the dry ice..The lady says she has 10lbs and to wait..she comes back holding two bags of dry ice in her bare hand..so much for the welding gloves..OK so I load the dry ice into the cooler and expecting it to last for quite a few warm days and it just didn't make it...So what did I do wrong?..I figured it to be alright that the dry ice was already bagged..but that doesn't work..

Dry ice wint last very long if its not super cold. What I use it for is the same set up ooi had which is to make my wet ice very cold and last longer. My dry ice in my home made cooler last about 12-16 hours but it makes everything else so coldbthat 20 lbs of my wet ice will last 3 days. I could make it last longer if I kept it fuller.

The beer next to the dry ice was frozen for a good long while.

The CO2 gas from melted dry ice has an expansion ratio of about 1500. It will force itself out of the lid. Keep your cooler closed as much as possible. Place frozen items in the bottom. Avoid opening the cooler as much as possible. Place a towel over the top of your contents inside the cooler. Insulation is your friend.
