ElectroBOOM Explains the Science Behind the Railgun—and then Makes One


A railgun like those being researched by the US Navy uses a form of electromagnetic energy to hurl projectiles at speeds exceeding Mach 7. As you can imagine they’re pretty dangerous so the perfect weapon for YouTube channel ElectroBOOM (aka Mehdi Sadaghdar) to make then. After explaining how they work, Sadaghdar sets about building one.

Although, don’t expect Mach 7 from this, it’s a much more timid affair.
