Wall Of Death

Hi, Crafters! I'm here with another cool creation. this one is called the Wall Of Death. Visualize this. A pack of Creepers is passing by your home. You know you can't attack them without blowing up your home. What do you do? You just repeatedly press a button! Before you know it, they're all dead. here's how to make that happen.

1.  First, place dispensers in your house's walls with the backs where you can see them while inside your house.
2. Then, use redstone reapeaters and dust to wire all the dispensers to a single button.
3. Next, fill the dispensers with arrows, or for a more destructive alternative, fire charges(but don't do that if your walls are made of wood).
4. Finally, press your button and the arrows or fireballs should fire.

I hope you enjoy this trap!
