sorry

okay so i don't know if this is physics, i kind of have a feeling it might be chemistry...but okay. so we were in these dorms at a community college for states and so it was like there were 4 beds, 2 on each side. So there were like two rooms and then in the middle was the tv, kitchen, living room or whatever you want to call it. So we were in the middle room and then one door to one room was open and the other door to the other room was closed. one of the girls from a different room came into our room to sleep for a while so she went in the room (the one with the door opened) and then she closed it so she could have peace and quiet. So when she did a few moments later the other door that was closed opened! i was freaked, but my friends told me that it was the pressure that made the door open. =]

Improvement

this past saturday was vars champs for swimming...
my past post about swimming talked about how i lost the momentum on my turns because of the "lever arm" known as my leg. Well as ive been practicing, my turns feel faster and more powerful. As i watched the video of my turns in the races from Saturday, I noticed that they were quick and I did not lose any momentum while going into the next lap. The increased lever arm increases the torque which increases the speed that my turn goes which makes me keep my momentum going in rather than losing it =]

Today

Okay so for most people today was the superbowl...
but yeah i did not watch it...well last night i went to the Chris Brown concert and there was this disc thingy he went on that spun and stuff but i decided to do something that is more recent...
STATIC ELECTRICITY. haha
so as i was sitting down i turned to my friend and noticed her hair was sticking up on account of the attraction to the balloon. then people were chuckling at me because my hair was sticking up also. i am guessing that these balloons were highly negatively charged because one, my head and the balloon weren't that close, two i kept putting my hair back but it kept on going back, three i tried "grounding" the balloon but it only reduced the amount of hair that stood up. haha. oh by the way in the picture above, someone rubbed the balloon on my head just for this picture..how lovely. hehe =]
