help with .next() or similar

I have an unusual situation.  I need to increase the font size of every word in a sentence, one at a time, everytime you click on the page / div.  any ideas ?

my closest idea was to wrap each word in a <span> tag and then use .next("span"), but that controls all of spans.

If i had  <span>word one</span> <span>word 2</span>, how would i style one span at a time by clicking a single button ?
