What You Need.
1 Transparent silicon
4 CPU fans (40cm x 40cm)
A Blade
A Pencil
A Ruler
4 pieces of cardboard (29cm x 5.75cm)
Electric tape
Packaging tape
Aluminum tape (optional)
A Compass
12v Power supply
2 pieces of cable (66cm) and (23cm)
Cardboard box

Step 1: The Box

First you'll need to completely seal the box with packaging tape. This way the air won't escape through any other hole.

Step 2: Intaling the CPU Fans

First, mark where the fans will go and cut just the hole. Now put the fans on with silicon to seal the edges well. Let the silicon dry for about 12 hours for best results. When the silicon drys, connect the cables together with electric tape. Than tape the long wire so that its not hanging.

Step 3: The Legs

Fold the pieces of cardboard every 6cm and make a triangle and glue it with silicon or tape (whichever you prefer). Now cut 20cm of aluminum tape and wrap it around each leg. Than glue all 4 of them to the box with silicon and wait for about 6-12 hours depending on how much silicon you put on each leg.

Step 4: The Air Holes

Draw squares of 2cm x 2cm. Poke holes with a nail or something that's at least 5mm in diameter where every line meets.

Step 5: The Chip

You can use a disk from the holes that you made for the CPU fans. If you want to make them even more slippery than you just have to put tape at the bottom of the chip.

Step 6: The Finnished Instructable

Now you just have to add the borders so that the chip doesn't fall out of the box and the goals can just be the bare ends of the box. The mallets can be from a bottle cap to a toy car wheel.
