Yes....the cannon definitely rattles windows
many years ago, I fired the gun on New Year's Eve and invited all the neighbors. About 30 or 40 people showed up and a great time was had by all. However, in the morning on New Year's Day, no one who had parked on the street or driveways over night could start their cars. All the glove boxes had popped open, the little light came on (long before LED bulbs), and everyone's car battery was dead. I spent the whole day charging batteries and jumping cars to get everyone operational again. From then on, everyone would always go out and check the glove box door in the car after firing the cannon and before going to bed.
And Daryl, yes the quill tube is very fast and it is not just filled with priming powder. Filling it completely makes it burn like a fuse. I make these quills by pressing 3F onto the sticky side of a narrow strip of tape and then I pull the the tape through the straw with a piece of string. The result is a hollow passage lined with gun powder. As the first portion light up, the hot gases are blasted through the hollow center and light all the rest of the powder almost instantaneously. I also dope the top end with a little smokeless powder which takes light from the glowing end of the linstock much quicker and more reliably than black. Here is a still frame of the quill tube firing.....
