The special, secret way to keep cool

Dip your arms (or as much of your body as you like) in cold water, then aim a fan at yourself and feel the cooling power of evaporation and latent heat. This should be taught in schools. I mean, they taught us about these concepts, but if they'd directly demonstrated this scenario it would have helped consolidate the concepts in our minds, while also having great practical value for our futures in a warming world.
