Remember those Duplo legos that Owen found stashed in the garage? For several weeks, Owen has been building stack after stack after stack. And getting more and more frustrated that the towers seem to topple for no apparent reason. At 20 months, he hasn't quite mastered basic engineering principles like the need for a solid base or the proper use of support beams. The construction methods also leave something to be desired as one hand usually pushes the tower over while the other hand is reaching to put ONE MORE block on the tipply top of the tower. It's great fun, but the towers are getting old. Two engineers just can't leave those legos alone and more advanced objects - cars, airplanes, boats, etc - are emerging on a regular basis. The other day, I created a pretty sweet helicopter (no photo, sorry) - good enough that Scott asked me if I had looked up a pattern. Ha! Scott's creation below has been Owen's favorite by far.
