Diet Coke and Mentos "Failure"

This year, for Van Dyke's Sports Camp VBS, we're doing a more general "Science Olympiad" instead of just Robotics. Tonight we played with Diet Coke and Mentos. I built a half-dozen nozzle rigs like this. The one in this video has a diagonal slot cut into it. The pressure from the Diet Coke was enough to knock the rig over and the top of the nozzle popped off. Then the bottle took off across the parking lot. It was cool enough that we spent the rest of the time trying to get another bottle to take off horizontally, without much success.

Luke McCown

It was great to see Luke McCown do great today. 29 of 37 for 313 yards, 2 TDs and 1 interception. Luke spoke at our church's Sports Camp two summers ago and hung out afterwards, signed shirts, and talked with the kids (and dads). The next day at practice he tore his ACL and could have easily never played another down in the NFL. The kids at camp made him a big get well card.

At the time it didn't make for a very inspirational story for the kids. See kids, if you work hard, stay out of trouble, go to church, and accept Christ, you too can have a career-threatening knee injury. So I was glad to see Luke have a great day today. I sure would love to see him back at our Sports Camp again this summer.
