"You can't see the whole sky through a bamboo tube. - Japan"

An interesting conundrum, certainly. Can you see the whole sky through a bamboo tube? What about a different kind of tube? Hmm... This calls for experimentation. For science!

After experimentation, I have determined that, indeed, you cannot see the whole sky through a bamboo tube. Myth Confirmed!
