A fun way to spend a rainy afternoon is building an indoor skate park out of cardboard to use with your finger skateboards. Finger skateboards are exact replicas of full-size boards, and you can even use your fingers to do basic skateboard tricks on them. The best way to maximise your fun is to build a park full of ramps and grind rails. You will need only a few tools and supplies to build your park.
Take a piece of cardboard and cut out three "L"-shaped pieces that will be the frame of your quarter-pipe ramp.
Cut a long rectangular piece of cardboard to use as the base for the frame. Glue all three "L" frame pieces down on top of the cardboard with the bottom leg of the "L" being the part that is glued so that the frame is standing up.
Glue the manila folder to the cardboard frame of the quarter pipe.
Cut a length of coat-hanger wire and glue it to the top of the manila-folder piece you used to make your quarter-pipe surface. This will be the coping of the ramp that you will be able to do grinds on.
Cut a piece of cardboard about seven inches in length and then roll it up and secure it with tape to make sure it does not come apart.
Make two 1-inch rolls out of cardboard and tape them to each end of the bigger roll you just made.
Cut two square cardboard pieces and glue them to each of the small rolls you taped onto the grind rail.
