Things to do for free in Orlando today, Tuesday April 26th?

Heading to orlando for the day but i dont know what to do.A friend and I just want to get away from our area and visit orlando bu we have very very little money. What's there to do in Orlando today, April 26th? I am 20 and she is 19 if that helps any. Nothing boring like meuseums or anything, and the beach is over-rated. We live in Fla as it is and the beach is an everyday thing...Any help???
