Well, it's been more than a year since my previous tutorial set off and we created the first ever barreled TNT cannon. Now for another design that'll knock your socks off... A RAILGUN! For its size, it is probably the single most powerful cannon in Minecraft, and hilariously easy to build. I guide you through the design and firing of one of Minecraft's most powerful cannons, designed by me!

Specs ~
- Near instant firing as you press the button
- Fully adjustable propellant load
- Extremely powerful
