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
-9v Duracell battery
This instructable was a little bit rushed, and will be made using rechargeable batteries in the future.
-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
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
-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.
Step 3: Coating with Plasti Dip
Also tape any other holes that you want to cover with Plasti Dip using electrical tape. Electrical tape is somewhat elastic, so it easily shapes around odd crevices.
After everything is taped, paint the Plasti Dip onto your circular case using a paintbrush that you don't mind ruining- this stuff does not come off easily. The Plasti Dip will give it a rubber finish, allowing better control of the puck.
When the Plasti Dip is dry, remove the bottom piece of tape and use an x-acto knife to cut away any excess rubber.
Step 4: Mounting the Propeller
I used hot glue to mount it and a large plastic spacer (red) to raise the propeller up since it was slightly touching the ground.
Step 5: Add batteries and wire it all together
Glue the batteries down and wire the motor, switch, and battery together.
After everything is in place inside the cap, drill a few holes to allow air in.
