[FRIAM] Science question...re: cold neck scarfs

[Robert Holmes]

If you really want to blow your mind, consider these mesh cooling towels:

When you've been wearing it for a while and it has warmed up, you take it
off, give it a sharp "snap", and it's immediately cold again.

I use one when the temperature is getting high in my (non-air-conditioned)
house and it works a treat.
