Cylinder full of hops pre-faucet?

[jkpq45]

OK, so two questions:

I've seen this cylinder full of hops that a pale ale will pass through before exiting a keg faucet. What is it actually called/how do I build one?

How does one prevent excessive foaming? It seems like this contraption would cause extreme turbulence (or trubulence, depending on the level of filtering....)

Thanks,

I am not sure how to build one, but I can say it is called a Randall.

The common term is Randall. Here is a link.

Randall the Enamel Animal!

I so badly want to find a bar with this option. I don't drink near enough or have enough people interested to try this myself.
