The house was a buzz; the hum of learning.
Thirty minutes later we had two experimental cable cars made from Polydron Revolution, complete with a make-shift pulley system on a spare piece of rope from the "junk" box.
The wonder and excitement of trial and error, learning from mistakes and purposing to make it better. Patience and perseverance necessary. Collaboration and deferment to another's idea.
I can create. I can learn. I can ask questions.
Indeed, thirty minutes mattered, and made a difference.
