1st Submarine Built

Grab your promotional submarine stress balls and get ready for a wild ride, as today we celebrate the birth of the Submarine. Submersible ships are quite amazing, what with all the hydro-pressure they can withstand and the rigors of staying oxygenated whilst underwater. The only thing they need now is cable access! If I was stuck underwater for long amounts of time, I'd at least like to see a little TV! Although a nice customized book doesn't sound so bad either...
