Cold crashing without a fridge

[Whatsgoodmiley]

I'm wanting to cold crash my hopped mead but I don't have access to a fridge (especially not a temp controlled one). I am thinking I could place my 5 gal carboy into a larger bucket, fill it with ice, and insulate the bucket and carboy with towels and replace the ice once or twice a day. Does anyone have any better ways (low cost) to keep the temperature around 33-40 for a few days to a week?

Lots of threads on this topic. This one seems to have the most responses. Sounds like they're doing similar stuff.

A week seems like overkill for a cold crash, if you ask me, though. A day or two should do the trick.

Oh, wait. You said mead. That might be different. I only do beer.
