Experimental Archaeology is cool. About as cool as the Internet, I would say - there are so many questions about our history still unanswered, and quite a few of them are suitable for designing an archaeological experiment around them.
Plus it's absolutely exhilarating to try out things and find out things at the same time - even if the trying out and finding out involves lengthy mind-numbing and tedious work. (It's a scientific method, after all - you don't get only the fun of doing, you get the work of analysing too.)
And then, impressive things can happen. Plus a successful archaeological experiment is almost always of interest for the public - so it also helps getting people understand how varied and interesting and yet unknown the past is. Case in point?
