Grandpa and Matthew

Jonathan's dad came to visit right before Christmas.  He came for the warm Texas biking climate, but he picked the only cold week of December!

While here, he and Matthew worked on a science project.

Behold!  The Ping-Pong Partner! We can't call it a "ping pong ball gun," because guns are Not Tolerated. But who can find fault with a ping pong service return practice partner?





They spent hours working on it together, designing, tweeking, and refining. I'm really not sure who had more fun, grandpa or Matthew.
