He said wanted to build a waterside with them. We bought a few pipes and some fittings and this is what happened.
I cut them into smaller pieces using a saw.
We laid them out on a board and then used brackets to attach the pipes to the board.
I left them loose enough so we could rearrange the pipes if we wanted to.
He took it apart and changed it around in many different ways.
This activity kept him busy all afternoon.
When it gets warmer here I am going to make this a part of his sand/water table.
It eventually became a duck pond. :)
