Im gunna do something somilar with wood and plexiglass...
Heres what you need:
plexiglas or hard, smooth plastic
screws or nails
Okay. These plans are for a straight rail, but can be modified to create kinked variations. First, you want to buy several 2x4's. for example, If your rail is gunna be 10 ft long and 2 feet high, then get 2 10ft long 2x4's and another 2x4 that you can cut into 2ft high sections. You also need a couple of spare pieces for the 'feet' of the rail. Refer to the diagrams below for the layout. Then simple screw or nail the 2x4's together. Now your half done.
Here are the diagrams:
