Musket Firing Demonstration in Slow Motion at Fort Frederick

Read Now

Muskets were a firearm used for over two centuries in several armed conflicts including the Civil War. In the video below you can see a demonstration of the firing of a musket in slow motion at the fort of the Fort Frederick State Park in Maryland.

The firing mechanism of the musket relies on a hammer (cock) that contains a piece of flint rock attached to its end. The hammer is pulled back into a position of tension (cocked position) thanks to a spring mechanism. When the hammer is released by operating the trigger, its flint head hits a structure called the frizzen, pushing it back and generating a spark that ignites a small amount of gunpowder under the frizzen in a space called a flash or priming pan.

In the video below, this is the first explosion that you see near the rear of the musket. Once the flash pan has ignited, the flame travels through a touch hole or vent and ignites the powder within the barrel of the musket, which results in the firing of the projectile. This is the second explosion in the video which comes out of the muzzle of the musket. You can even hear an echo of the explosion from the sound bouncing off the barracks and walls of the fort.

A Sun Glitter Pattern in Slow Motion

A sun glitter pattern is formed when the light of the sun is reflected off the surface of ripples in the water. A smooth body of undisturbed water would produce one reflection of the sun. But the chaotic overlay of many ripples on top of each other produces numerous reflections of the disk of the sun constantly appearing, moving, and disappearing. The most recognized, photographed, and written about glitter pattern is the one produced when the light of the setting sun is reflected off an ocean or lake surface. But glitter patterns can be found anywhere there is a liquid reflecting light including Saturn’s moon, Titan, which has lakes of liquid hydrocarbons. In our planet, glitter patterns are used to produce more accurate weather forecasts.

In the video below you can see a glitter pattern in slow motion on the waters of Old Farm Creek in Rockville, Maryland.
