Brown Stair/Marble Extension

For those of you who don't frequently check out the other blog (OMS Daily), we did a cool brown stair/marble extension I remembered reading about at The Wonder Years long ago: rolling a marble down the stair as a control of error.

When we tried it, we were delighted to discover a musical surprise. :)

Thanks for the great idea, Amy!
