Today’s Living Social deal is half off a membership to the Franklin Institute. The membership pays for itself in just a few visits, plus you’ll get free or discounted passes to their special exhibits and the IMAX theatre. It is also reciprocal to over 250 other science centers, list here. The Science Center in Baltimore is included!
