B.A.D. : A Video Guide to Constructing and Firing Your Own Backyard Artillery Device

The Backyard Artillery Device Model 1 (also known as 'The Bad One') is a self-contained, electrically fired smoothbore gun powered by a fuel-air mixture of high-octane petrol and pure oxygen.

Using less than a teaspoon of fuel for each short, the BAD can launch its 'projectiles' (full beer or soft drink cans) nearly 300 yards with just the press of a button.

This video takes you step-by-step through the process of constructing, testing, loading, and firing a BAD.
