It was pretty easy to construct, and I just used things we had around the house. To start, I found a big ol' drill bit, drilled some holes in some old buckets and a water bottle we lost the lid to, then created the tracks/gutters with an old wrapping paper tube split down the middle. I am intending to purchase some guttering or something else more substantial next time I get to the hardware store.
So, back to the process. Once you drill holes in the objects, run bolts through them, through the holes in the Masonite, then fasten a nut on the back of the board. You really just want one hole in each object so it can teeter-totter and be positioned as needed. I suppose you could do this same project with a solid piece of wood that you drill holes in wherever you want them for the same effect. I think it'd also be cool to paint the board with chalkboard paint and have the kids draw the path of the ball and make engineering type marks on it. So as you can tell, I will be adding more and making it look a little nicer, but for a 30 minute project, it is still pretty fun.
What was even more fun is to watch my son jump up and down and get super excited when he made the ball go where he wanted it to by changing the angle of the ramps. He also thought of adding the Kinex rods to make the ball do even more crazy things.
