My brother recently bought some guinness draught beer. It had a "rocket wizzle" or something like that in it. What is the rocket wizzle's purpose? Anyone know?

it's a nitrogen cartridge so it pours like it does on draught.
here's the science of it..........
This is the way the system works: The 16.9 ounce can (containing 14.9 ounces of beer) is fitted with a small plastic device (Guinness calls it a "smoothifier") which sits in the bottom of the can. This device has a pocket or cavity which is open to the atmosphere via a pin hole in its top. The can is evacuated of oxygen and filled with beer. Prior to sealing the can, a dose of liquid nitrogen is added to the beer. The can is closed and as the liquid nitrogen warms a pressure is created. The pressure forces about 1% of the beer and nitrogen into the plastic cavity. When the can is opened, the pressure is released and the small amount of beer in the cavity is forced back through the pinhole quite violently. The agitation created by this "geyser" mixes the nitrogen with the beer in such a way as to reproduce the tap handle character.

I drink Guinness. I think you are referring to the Widget inside the can? This helps the flow when pouring to give it the unique Guinness Head. The widget is like a plastic ball. Hope that helps

It's a widget, and it's supposed to mimick the cascading effect that stouts are famous for when found on tap.
