A Pendulum Wave. Beautiful to watch. See it in action in the attached video.
It comes with three sets of Pendula and a pusher which slots into the base.
To assemble put an end cap onto the post and then all the pendula with spacers inbetween. Add the second end cap and slot the post into the stand.
Make the pendula swing using the pusher or by simply sliding the stand forward and back.
