Give science a hand

Right now the website BigThink is involved in a DonorsChoose program where the company Pfizer has agreed to donate $1 (up to $10,000) for every vote the videos on the BigThink page receive. There are two weeks left and the tally so far stands at about $6,000, but I'm sure that they can hit the $10,000 goal before it's over. They need your help, though, so head on over and vote (you can vote for each of the 10 videos once, which means that you can make up to $10 for the program).
