the dry ice will keep better in the freezer than it would at room temp (obviously)..but because the dry ice is frozen at -75 degrees and freezers are generaly around -4 degrees, it will still 'melt' a little. but being that it is kept in an isolated area it wont be so bad. freezer woud be the best option. also as stated the pellets will disappear much quicker than a block, so go the block.

maybe buy a block beforehand and test it out. let us know the results if you do :D

Will do. Plan to buy a 2.5kg block $10 and measure the temp in the freezer and weigh the block each day to judge percentage lost at that temperature. Will post results.

dont put the dry ice in your freezer it stops the motor from working as 4wdnut said dry ice is frozen at -75. It may wreck your freezer.

wrap the blocks of dry ice in a few layers of newspaper. Place them into an esky and don't open it until you need to. Also store the esky in the coolest most stable temp location you can find. It should keep fine for a few days before you need to use it.

Once you do use it always try and keep a few layers of either newspaper, tea towel etc between the dry ice and your food as it will freeze anything it comes in contact with. Then stack your eskies with the stuff you want to keep frozen for longest at the bottom and then stack them as required from there

closed pollystyrene containers keep it for a while aswlll.. we often buy a block and a few scoops of it. last tiem i left it in the tub there was still some left 3 day later... which was left in my tin shed...

(aparently its not good for plastic eskys as it freezes the plastic and can make it shater)

also put some dry ice into an empty coke bottle, and about 1/4er water, put the lid on and throw...

as chopper says...F*CKIN' BANG!

and i also wasnt aware that it can wreck your freezer...lol sorry.

EDIT: its probably also a good idea to get a facts sheet when you get your dry ice, as there are precautions to take. storing it in an airtight container is a no-no as it will also go bang, also when travelling with it in a car you cant have your windows up as it will plainly suffocate you. best to get a fact sheet, i know BOC supply these.

Thanks for the tip Dromana7411 on the coke bottle. I found a site that shows what can go wrong with dry ice bombs. http://www.dryiceinfo.com/Pictures/dry% ... injury.jpg

They say it has an explode time from 2 - 120 seconds. Sounds like something I would watch someone else try from a distance. Will keep it away from the freezer though.
