“How does it come apart?” You’ll be asked this question each time you hand one of these cubes to a friend. You’ll answer, “Well, you just hold it like this, then pull.” Your ability to read wood grain will help you to quickly identify which sides to grab. Your friend will be mystified. That’s just one of the small pleasures in making these airy nothings. They really don’t have a purpose other than to tickle your fancy.
