A great video showing how NFL footballs are made. Fairly creepy when he shows the entire side of a cow, but good to know how many animals it takes just for us to watch a game.

I came across the Trans-Atlantic Slave Trade Database while reading Henry Louis Gates Jr.'s opinion piece on slave reparations in the New York Times.
It has great statistics, charts, maps, and more. This is a wonderful resource for anyone teaching about the trans-Atlantic slave trade.
