A group of engineering students from Purdue University recorded that their licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. They tried the same licking test on 20 volunteers and found that the average licks to the center were 252 licks.

Serves 4 to 8 people depending on the size of the roast. Note: For medium-rare prime rib, we want to take the roast out of the oven at 120Â°F, and it will continue cooking until it reaches 130Â°F. If you prefer a medium prime rib, take it out at 130Â°F with a target temperature of around 140Â°. When you're ready to cook, set the roast in a roasting pan with a rack, fat-side-up for a boneless prime rib. 2  Or for a bone-in prime rib, skip the roasting rack and just set the roast bone-side-down in the roasting pan.
