Have you ever rappelled an underground waterfall? Do you know what the difference between a stalactite and a stalagmite is?

We understand that your time at Splash is finite and valuable, which is why we're offering a class in an important life skill. Welcome to underwater basket weaving. For years, the sacred craft of underwater basket weaving has been ridiculed by admissions offices across the nation as the de facto example of a worthless educational pursuit. Our mission is to break this stigma and expose the rich world behind this craft. We're also really amused by the concept of *actually* doing underwater basket weaving, so here we are. For more information on this ancient craft, see here: http://en.wikipedia.org/wiki/Underwater_basket_weaving
