the wet-dog shake

npr's 'all things considered' had a pretty adorable interview yesterday: georgia tech graduate student, andrew dickerson, has been studying the way animals of different sizes are built to shake off water to dry their fur. bears and dogs shake at about 4-5 hz (in this case, the number of shakes per second) and the smaller the animal, the faster the hz. cats shake at about 6 hz where mice dry themselves off at 27 hz! 27 shakes per second!

this is the link to the npr page with info on his study (which he believes could improve the engineering of washing machines!) and a cute video of animals shaking in slow motion :)

xox, c

ps. read the comments at the bottom of the npr page...people getting fiesty!
