To really understand what the widget does, first you have to understand how Guinness is served on tap.
Guinness is a beer with relatively low carbon dioxide content. Low CO2 beers generally have gas added to them as they're released from the tap (called brewgas - a CO2 and nitrogen mix usually), which gives a thick, creamy head to the beer. The head is very important for flavor and texture of the beer. Guinness in particular needs a half-inch head to get the optimum "creaminess." Normally, it's not possible to add the brewgas to a canned or bottled beer; it has to be added just before pouring to agitate the beer and make a thick head.
Canned Guinness solves this problem using a "widget" - a plastic ball that holds some brewgas inside it. When you open the can, the change in pressure forces the gas out of the ball. The extra shot of gas, combined with pouring it into a pint glass, causes it to develop the same head that it would in the pub. (Guinness cans actually have instructions on the side, telling you to pour the beer instead of drinking from the can.)
The rocket widget is essentially an improved version of the ball widget. It still gives the initial burst of brewgas when the bottle is first opened, but the new design gives an additional "squirt" of gas each time the bottle is turned upward, recharging the head each time you take a drink. The result is that you can drink Guinness straight from the bottle, without sacrificing the head and impacting the flavor.

What is the white ball in the Guinness beer can?
This is what I got off of the guinness.com website: Glad you asked. The widget is a plastic molded device that sits on the top of the contents of each can of GUINNESS® Draught. When the can is opened, a small amount of beer and nitrogen, trapped in the widget, is forced out through the beer, which creates the famous creamy head that you find on a pint of GUINNESS® Draught served in a pub. The widget gives GUINNESS® Draught in cans the taste and texture of a pub-poured pint at home. In GUINNESS® Draught in bottles, the clever little 'rocket' widget floats free in the beer to refresh the creamy head of your GUINNESS® Draught with each swig you take from the bottle.
Is a Guinness bottle with a rocket widget recyclable?
Yes, the Guinness bottle with a rocket widget is recyclable. To recycle it, simply separate the components (glass bottle and rocket widget), and place them in the appropriate recycling bins or facilities according to your local recycling guidelines.
Who invented the gas wiggit you found in Draught beer cans?
Guinness brewers Tony Carey and Sammy Hildebrand invented the "widget" in 1968. Slainte!

Is Guinness better than wine?
Guinness is beer, and you can't really compare beer to wine.
Why is there a floater in a Guinness draught can?
yes. The little plastic ball called a "Widget" was first patented by the Guinness company years ago to add the right kind of head on their thick and creamy stout, which is less fizzy than regular lager beers like Bud Light. When Guinness is canned the brewers add a shot of liquid nitrogen to help pressurize the can. As the pressure in the can rises, compressed nitrogen and beer are forced into the sphere through a tiny pin sized hole. When you open the can, the beer and compressed nitrogen within the sphere depressurize and are shot out into the beer. This disturbance causes the CO2 to bubble up which creates the foamy head at the top of the glass. The only thing left to do next is drink!
