Picture of Life Size Air Hockey. The Hover Puck
In this instructable I will be showing you how to make a Hovering hockey puck! Although the process of making this toy requires a lot of testing (finding a light enough casing, finding a strong enough fan etc.) it is very simple, cheap and easy to make :]

This toy is great for kids of all ages.
The puck is durable enough to play real indoor hockey with, yet lightweight enough to be used as an air hockey puck.

Step 1: Materials

Picture of Materials
First, gather all of the given materials:
-9v Duracell battery
                  This instructable was a little bit rushed, and will be made using rechargeable batteries in the future.
-Battery clip
-On/off switch
-A propeller and motor from an old RC plane/helicopter
-Smoke detector (can use other circular objects to case the puck, but i'll explain that later)
-Plasti Dip (can be found at most hardware stores)
-Large plastic spacer
-Hot glue

First open the 9V battery's metal casing as shown, using a plier. It is easiest to open the battery from the seam on the side.
If you want to see a video demonstration, check this out... JUST DO NOT CUT ANY OF THE LEADS ATTACHED TO THE BATTERY
-Cut off the plastic wrapping and put it to the side for later

Step 2: The Casing

Picture of The Casing
-Depending on the size of the motor and propeller you found, choose a circular casing which has a large enough diameter and depth to fit the propeller. 
-I chose to use the top of a smoke detector; it is fairly light weight, the perfect size for my propeller and also already has holes for air to -pass through.
-Cut out the center of the plastic case using a drill bit and an x-acto and sand down any excess bumps/pieces of plastic to reduce weight- The lighter, the better.

This makes me want to replace all the floors on my house with hardwood floors. This is clever, and looks like loads of fun!!

I want to make this for gym class. Please help me find a propellor and motor. I have everything else I just need the main component.

Woah where? I looked all over online and thought this toy didn't exist? Can you send me the link
I had one got it for crismis it was rechagibal but I lost the puck

Still cool to DIY!
I looked up it at that website (, it is $11.99 but it is a "low-friction" puck, it doesn't float like yours. Great instructable. Thanks!

I like your idea, have you tryed a computer fan or mabye a hair dryer fan. They are about the same size and it's probably cheaper to buy. Also mabye you should make the bottom of the puck more like a hovercraft to make it have less friction between the bottom and the floor.

Yeah, I tried a computer fan and it was too weak and also too heavy... haven't tried a hair dryer though.

Nice going - really cool how you solved the battery problem....

Thanks :] yeah keeping it symmetrical is very important.... before I took the 9V apart, the puck spun like crazy ha

The picture of this looks like an abandoned air strip in the desert. Does anyone see this? It is most noticeable in the thumbnails for this project.

This is sweet. I love hockey, this would be perfect for rainy days in the summer!

Thanks :]
Me and some friends had a small game in the living room last night, we made a few goals out of PVC.. it was awesome! haha
This is awesome! I want to make one!

It would be sweet if it had a secret 'skill shot' switch, which (when set off) would increase the propeller speed, causing the puck to fly up a bit!

Awesome job!
