Earth's most popular drink had a problem when people first went into space. It was relatively early that history had the first dog in space, the first woman in space, and the first marital consummation in space. However the first Coke in space ended in disaster. The problem with Coke cans is firstly to do with pressure difference. If you take a coke can into the hard vacuum of space, the pressure of the carbonated drink inside will explode the can, sending aluminum shrapnel in all directions, damaging satellites, shuttles, and especially astronauts in space suits [1].

If you sensibly open the can inside the pressurized cabin compartment then the gas escaping from the can's ring-pull will project the can in the opposite direction. Of course, you usually hold the can firmly tight when opening it, and so the whole system of yourself and the coke can is shot through the cabin. Eventually you figure out how to point the top of the can straight up and position your feet on the ground. You can open your can and absorb the pressure with your legs. Then you then come across the problem that the ring-pull is not perfectly symmetrical. The gas escapes from one side faster than the other. The coke can may twist from your grasp, spraying liquid sugar in a Catherine Wheel of gunk. Alternatively, you may be the one to start spinning [2].

Not to be defeated, the food scientists designed a widget which released the gas in a safe and symmetrical fashion. This is the source for the advertising campaign:

Widget, Its got a Widget,
A lovely Widget,
A Widget it has got,
A Widget.

[1]	It is rather silly trying to drink from a coke can inside a space suit when the coke can is outside.
[2]	This is the reason for those training machines which spin prospective astronauts in all directions at once.

Quite amusing actually. The beverage would come out as a foam spheroid, which would be played with by the crew. They would blow on the edges to make it spin, or just follow it around the cabin and sneak up on it and consume it. There is an example of one of the actual cans on display at the National Space Hall of Fame (or something like that) in Alamogordo, New Mexico, located near White Sands Missile Range.
