Who Knew Erasers were so labor intensive?

Whoa! Watching Discovery, my favorite channel, and that show How Its Made. They just showed how erasers are made. Did you know they use vegetable oil to help it break apart when you rub it on paper? And talc powder to keep them separated in the big mixer machine after their cut apart? And then they mix them up for 5 hours so that the ends rub together and round off the edges saving someone the time of having to do that themselves???? Seriously, WHO KNEW?! I Love this show!!!!
