A ripstick is a two-wheeled skateboard.  To ride it, you need great balance and a lot of practice.  To get on the ripstick, you take your right foot, put it on the ripstick, and lift it so it’s flat.  Then you push and quickly put your left foot on.  When you get on, you have to wiggle.  And to wiggle the first time, you might need to use your whole body.  Do not go downhill the first time, and watch out for cracks and rocks.  If you want to go faster, don’t wiggle harder or you’ll slip.  Just make longer wiggles.  Heads up.  You can’t stop.  If you want to go up and down a jump, make sure it’s not bumpy.
