The San Francisco Exploratorium had a Valentines Day special where they offered a class for members to take where you dissect a heart. My friend Jay's friend Judy is a member, and she signed up for the class. It is supposed to be for "families" so she brought Jay and I along. I met Jay at Mission Pie in the city, and Judy picked us up from there and we drove over. It was my first time meeting Judy, and she seems like a lot of fun. We got to the class a little late, but we didn't miss anything. About 10 minutes after we arrived, they gave each family a calf heart, and told us to poke our fingers into all the "holes" (like the aorta, the vena cava, the pulminary artery, etc) and feel for the valves. It took us a while, but once we figured out where the valves were, we were all really surprised. Then we had to string a piece of string through the left atrium, the left ventricle, and then out and through the right atrium and the right ventricle. Once we got that, which was hard might I add, we cut the heart in half and opened it up! We were absolutely amazed. It was not what we were expecting at all. I can't really do an explaination justice without being able to use some charades and hand motions, so I'm not really going to bother here. It was a really cool experience, though, and I'll never really forget it. What a cool Valentines day special for the Exploratorium to have! After the class ended, we spent another hour or so exploring the exploratorium itself, which is always a blast. We had a lot of fun playing with several exhibits and we left on a giddy high.
