Question Crushed ice.

8 months 2 weeks ago #41206 by AndyG
I normally bash frozen 2l bottles to get crushed ice but often only need a little so it's a waste. Whizzing ice cubes in a blender results in slush.
We hit on an idea and it seems to work.
Cut off the sleeve of on old but strong lab coat (my 'proper' cotton one worked!) Get a friendly technician with a sewing machine to close one end of the tube and fold/double stitch all the seams for strength. Put a nice hem on the remaining cut end to stop it fraying. The level of embroidery is optional. :-)

You know have a patent ice cube crushing bag that doesn't split when you hit it.

Throw in a few ice cubes, fold over the top a couple of times to make a loose parcel, place on the floor/table/whatever and bash with a plastic mallet whilst thinking of something annoying. The result is nicely crushed "dry" ice, not slush. Minimum quantity is about 2 ice cubes, maximum depends on how much sleeve they've left you on your lab coat :-(

Brilliant!
I usually end up crushing the ice in the 2L bottles and then trying to scoop what's not wanted into a plastic bag for later.

I'm still for belting hell out of a bottle, you can either save the surplus ice in a bag or use a 500cm3 bottle instead?

I like dry, powdery ice and if stored it tends to degrade and you need to break it up anyway. I don't have a reliable source of 500ml bottles and when I have then I find they often split when violently abused even if they're for carbonated drinks. 2l are still my go-to, this is just a fully green, reusable system for a few ice cubes.

Am I the only one who uses a proper ice crusher? I also keep plenty of crushed ice in the freezer for those last minute requests

I use a method I saw on the Scitech forum.
Freeze water in 1litre Carte D'Orr (or similar) ice cream tubs with lids. When crushed ice is required, dip 1 or more tubs in hot water. This frees the ice from the tube and makes it crack up. The ice is then tipped into a bag made from the leg from some old jeans. The ice is then broken up with a hammer.

We have a load of ice trays (from an old EMPA/ISA)
We have big black bucke, we pop ice into this.
We have physics large mass hanger with stacks 1 & 0.5kg on it (taped together)
We lift and drop this on the ice in the bucket.
It's satisfying.

Anything spare is put into in on of our two large ice cream tubs (old 2 to 5kg one, forget which size, the deep rectangle ones.)

that then comes back out for quick crushing if needed.
