The science behind the head on your pint from a beer engine

I bought a beer engine a few months ago and really like the beer I`m drinking from it. However it didn't come with a sparkler, I`m interested in buying one just to compare the difference.

cheers BB, my local HB shop has lots of bits and pieces so was thinking of asking him. When I bought the beer engine it had no drip tray, Cliff gave me one FOC.
