Here is a quick and easy way to incubate your eggs in Pokemon GO without leaving the house! I was surprised that this works, but it does. It will incubate your eggs at a rate of about 1 km per hour - give or take. Start it up, set it aside, watch a movie, and by the end a 2 km egg will be ready to hatch! I've included a video of the incubator in action in the very last step of this instructable so you can see for yourself that it does work.

What you'll need:

A fan
Rubber band
Screw driver (either phillips or flat head depending on the fan's screws)

Gather your materials and let's build this thing.

Step 1: Open the Fan's Casing

First thing you will need to do is open up your fan's casing.

Remove the screws. In my case they were on the back of the casing in each of the four corners. Keep your screws somewhere safe where you wont lose them. That way you can always put the fan back together later.

Now open the casing and stack the part with the fan in it on top of the other. This is to make sure there is airflow below. I've heard that you can start a fire by putting a fan down directly on carpet or cloth.

Step 2: Attach Phone and Start Incubating!

Attach your phone to one of the fan's blades.

Use the rubber band to attach your phone. Spin the fan slowly with your hand to make sure your phone isn't knocking against anything.

Obviously, make sure Pokemon GO is running and you have eggs ready to incubate, and then start the fan. I had mine set on low. Your eggs should incubate at a rate of about 1 km per hour, give or take. Watch the video in the final step to see the incubator in action!
