(this is for fun)
how many licks does it take to get to the center of a tootsie pop?

364

explanation:

a group of engineering students from purdue university reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a tootsie pop. twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center.

this is a good question! i'll do some research and come back when i have the answer!
