Love air hockey, but find the tabletop version a little confining? How about busting out the concept of a fan-powered hockey puck into a full-sized version? Here's how to make your own.
1. Cut a hole in a smoke-detector case. Make sure the hole is large enough to mount the propeller and motor from a remote-controlled plane or helicopter.
2. To protect the entire outer surface of the smoke detector, cover it completely except for the bottom rim with a coat of Plasti Dip.
3. Mount the propeller and motor in the hole with hot glue so the air is sucked through the vents of the detector and pushed toward the floor.
4. Solder six AAA cells in series using nickel tabs. Glue the cells in a round piece of plastic with ventilation holes, making sure the weight is evenly distributed.
5. Wire the motor, an on-off switch and the battery together, and attach the cap to the smaller end of the smoke detector. Place the larger end on the floor.

We want video! We want video!
Harumph!
Video can be found by following the "Instructables" link just below step 5.
Scrumpulate,
The flapping flying man had many videos and yet a fraud. It will be a long time, until I get that out of my head.
Still, I with you, I want a video too.
As someone who has played hockey for most of my life, I cant see this being very practical.
First, you would never want to use a stick on a hardwood floor like they have in the video as it would quickly be ruined.
Also, I doubt you could get that thing moving very fast without it flipping or it being broken.
Guess it could be used in very slow games and be fun for a little while. But anyone who is used to the fast pace of a regular game would not find this very fun. (at least I wouldnt)
Silly people, there is a video if you click the link to the Instructables site. And yes, it is awesome...
As the batteries begin to deplete themselves the hovering will become less and the puck will slow down. The time this happens is unpredictable and during a game that is unfair. Plus the thing looks kind of fragile should it actually be hit hard in a large basket ball wooden floor court. I suppose as a proto type it is interesting. I guess we will what will develop for the future.
