Andy doesn’t know what to think about this.

He examines the line of blocks…

…yet still hasn’t a clue. (How it stayed up, I don’t know!)

I show Andy how they knock down.

He still is perplexed!

I have a bag of 300 of these blocks. When I find a better place to set them up, I’ll see if I can get Andy “into” knocking them down! He usually  knocks things off of high places, and this looked like a natural for his amusement. I still think it is.
