This run is a twist on the long run of steps that flows down a wall–here the ball takes a lovely series of curves on its way down. I’ve shown all the steps, and given fewer words for this set of instructions with the hope that you can pop it up on the tablet or phone or wherever and let your kids (7-8ish +? ) give it a go. Enjoy!
