Redstone - No. 1

This is my new series of how to make redstone things! Today, we will be learning how to make a VERY annoying, door. So the materials you will need are:
-Redstone
-A lever.
-A Redstone Repeater
-A door

Place the door on a flat surface. Then, attach a Redstone Repeater right next to it,from the Redstone Repeater, attach the Redstone. Then at the end of the redstone, attach the lever. Pull the lever and it makes a very effective, annoying rattling noise that you can put under your friends house!
