Friday we tested the strength of our little popsicle stick bridge. It weighed in at a whopping 3 ounces. We began by filling cups hung from it's deck with little glass rocks. After filling the two cups with no apparent stress to our bridge, we began piling books on top of it. We stopped at 20 pounds worth of load, as the boys didn't want to destroy our creation and it was beginning to moan under the load a bit. So here in the second picture, you see engineering (trusses) and nursing (textbooks) peacefully co-existing. (Barton family joke!)
