Awesome tip submitted from Jeff, straight from his snowy backyard in Minnesota:
1) fill your nICE mug mold
2) pack it in a snowbank, up to the top.
3) come back 20 hours later.
Frozen solid, crystal clear.
It’s exciting how nature continues to show us new and better things: First it was penicillin from Brazilian rain forests, then rubber from the rubber tree in Thailand, and now nICE mugs from snow banks in Minnesota. Does the snow in your state make great nICE mugs too?
Thanks for the tip Jeff!
