They've been busy too...

This is a tower that my dad and brother built, at least, Dad built it, and Colin handed him blocks! :)
It's built with Kapla blocks, that are made to balance well. Their website explains how they're made.

So far the tower is still standing, but if Colin keeps admiring it, (very closely) it'll be going down soon! :)

And this would be why Colin loves Saturdays: Daddy's home!
