Freezer (Frosty) Mugs

My girlfriend went on a shopping trip to Christmas Tree shop today and got me some awesome freezer mugs to keep my beer nice and cold. We were discussing how well they work and wonder; is the space filled with water, and air, expansion room, or is it some sort of ethanol/glycolic solution?

Any info would be welcome.

I'd hate to have to drill a hole in one to figure it out.

    I have some of these that are clear and there is about 20% expansion room. It's not water in there, it looks to be some kind of thin gel or something. I'm assuming it's clear, but the mugs I have are tinted so I can't really tell.

    I have some - they're filled with 80% some unknown fluid and 20% air/gas/empty space.

    Since you were discussing how well they work: Whatever you put it on will get wet from the condensation. This may be more or less annoying to you than it is to me.

    Ice packs and freezer mugs are generally filled with water plus a few ingredients that lower the freezing point a bit and inhibit bacteria. You won't find one filled with ethylene glycol for two reasons. One is it would kill you in a particularly painful way if ingested, and two is it wouldnt freeze in a household freezer... So yeah, not a desirable combination for a freezer mug.
