At the Olympic Games, the gymnasts have a honey bottle in or around the chalk bucket. The honey is used like Stick-um; to provide a better grip on certain elements in "hanging" events. Gymnasts always chalk up both their apparatus (to make it easier to swing on) and hands (to prevent cracks in the skin). By placing a little honey on either their fingertips or palms (or both) gymnasts can get an even better grip on the rings or bars while swinging.
The Olympic Games are great - I'm in awe of all of the athletics. But my favorite this year has to be the Beach Volleyball - those girls are awesome.
