Playing with Marbles

Peter challenged me to use all the pieces in our marble run -- to see how high I could build it. 
I had to get on an adult-sized chair to put the marbles in.
He just puts them in wherever he can reach.
We've lost so many marbles -- I think most of them are under the piano.
I held the camera out above my head to get this shot. This is the tallest marble run I've ever built.
Just an example of something we do when the weather is gnarly.
Build a very tall marble run and then go jump on couches.
