Rambach, Steven asked the Naked Scientists:
Hey. Upon serving various carbonated drinks recently, I was reminded that root beer tends to produce foam much faster and more than many other carbonated drinks when poured into a glass. Why is that?

What do you think?

I've never had root beer but there may be something about its make-up that gives it a surface tension value that favours the formation of foam - the other variables could be the amount of carbon dioxide they dissolve in it as well as the temperature it's served at.
