Fort Ticonderoga Continental Army cannon proofing demonstration

A demonstration at Fort Ticonderoga in Ticonderoga, NY of how a cannon in the Continental Army was proofed. Proofing was testing to see if the gun was fit for service. The barrel would be loaded with more powder or shot than what was normally used to see if the barrel could take the pressure, then the barrel was checked for imperfections or cracks. The gun being proofed is a 3 pound cannon.
