Do not try this at home! LC
Toast a piece of bread in a traditional style toaster. Hold your dry hand a few inches over it, enough to warm your hand but of course you don't want to burn it. Now do it again, but your hand is wet but not dirpping wet. After ten seconds or whatever it takes to warm it up but not dry it, take your hand away from the top of the toaster and see the difference. If you can get your hand outside quickly in cold, windy conditions quickly, that would presumably an even better idea. You can also wet a glove or gloves that would be most similar to the kind of clothing the 7 less well-dressed members of the group were wearing, and again, hold it over the toaster until you warm up, then take it away and compare how that feels to when you did it with a dry hand (again, putting the hand outside in cold/windy conditions would be better). I won't say anything more to avoid introducing bias.
