Tinkertoys, etc.

Here's a nifty little invention that Trev put together with Tinkertoys today. The yellow grabber thingy (like my technical language?) is held up by a rope that is anchored in place.
Pull the anchor, and the grabber plummets to earth.

When he grows up and invents something that makes the world a better place, I'll be able to show folks these photos of his early tinkering.
P.S.  I got a job!  I am going to be a Middle School teacher next year!  I am approximately 53% relieved and 47% terrified.
