In one sentence, describe what the following article is about:

Any sort of sink. You can use that sink as a bowl for the fingerboard. Make sure the covers of the books are facing each other. This creates a mini ramp. These can be the rails. If you can't get drawer or cupboard handles, squish a ruler between two books.

Summary:
Find a sink. Get some 300-400 page paperback books. Open the books so they can be used as a mini ramp directly adjacent to each other. Get the handles from some drawers or cupboards. Stack some books on top of each other to create a staircase. Have fun in your homemade skatepark in a sink!
