Things You'll Need
Instructions
Building Ramps
Take an empty cereal box and remove the flaps from its top.
Cut two-thirds of each corner of the box, giving you four flaps.
Turn the box so the flaps are pointing towards the ground. Lower the box, pressing it into the ground so the flaps arch away from each other.
Secure its position with tape when the arches are at your desired angle.
Building Rails
Cut off the point and eraser of a pencil with scissors.
Attach the pencil to a binder clip so one end sticks out from the back.
Tape the pencil in its position.
Place another binder clip on the other end of the pencil. This is your rail.
