In the 1970s, football players used a product called Stickum to help them hold on to the ball.

In 1980, the outstanding Oakland corner Lester Hayes smeared an adhesive called Stickum on his hands and consequently led the league in interceptions.
According to legend, the west-coast team tried just about everything to keep its archrival running in circles: Some say that the Raiders coated their palms with a gluey substance known as "stickum." That way, they could catch the ball easier than their yellow-and-black-clad opponents could.
Super Glue, believe it or not, has been around for 30 years, being marketed under various names such as "Eastman 910" or "Loctite 404," while today almost any supermarket that's worth of the name carries at least one brand of the stickum. (And stick it does, as those of us who are fumble-fingers well know, having had to razor the digits apart if we weren't quick enough with the nail polish remover.)
* Put stickum to fasten breakables to shelves (museum wax, or "Quake Wax").
Wash plate thoroughly to remove any stickum; dry in drying rack (this will prevent lint from adhering to the glass).
