Check out this video to see how a beer bottle can be opened using a rifle, making this one of the most american things a person can do.
In the video, the muzzle blast from an SKS is used to remove caps that are placed on beer bottles. In many circumstances, a person would normally use a bottle opener to take a cap off, but there are some other methods that can accomplish that same task and this is most definitely a unique one.
The high pressure gasses that are released after firing is all that is needed to pop the cap off of the bottle. The bullet never touches the glass because that would make the bottle shatter.
