AI Thread Summary
The discussion centers on the optimal conditions for packing snow to build snowmen, emphasizing that snow packs best when temperatures are above freezing. The unique properties of water, particularly its expansion upon freezing, influence how snow behaves under pressure. When temperatures are close to the melting point, applying slight pressure can cause the snow to melt slightly, allowing it to re-solidify and hold together better. Participants share personal experiences of building snowmen, noting that wetter snow, typically found near freezing temperatures, is ideal for packing, while dry snow is less effective regardless of temperature. The conversation also touches on the challenges of making snowmen in colder conditions, where snow is less sticky, and the fun memories associated with snow activities. Additionally, there is a mention of various snow types and their moisture content, with insights from snow scientists on the best conditions for snowball making and snowman construction.

I'm impressed that we had to come this far into the thread for someone to offer an actual explanation! :smile:
The post uou quoted was only 12 days after the inception of the thread. Although that was seven years ago.

Oh. *cough* I really should get a pair of glasses. I have to admit my age.
