Have you ever woke up in the morning and just decide to go to your backyard to build a portable rail gun just for the fun of it? One person in the name of Jason Murray did just that. In his Youtube video, he showed us the overview of the 1.25kJ rail gun he just made alongside some other impressive specs.
Without any surprise, the rail gun does not perform as well as the actual one used by the Navy. However, its ability to fire shots at 128 feet per second is quite impressive for a homemade rain gun. If you want to see how he did it, have a look at the video on the next page.
