(walking home from playground)

Zachary: What would happen if someone crashed the Milky Way?
Michael: Galaxies do crash.  If you have a strong enough telescope and know where to look, you can see some colliding galaxies.  We can look on the internet at home to see some pictures.
Edwin: I want a telescope so strong that it could see *molecoles*!
Michael: That's an electron microscope, and their very expensive.  We don't have one.
Edwin: We should buy one!
Michael: They're much too expensive for us to buy, Edwin.
Zachary: Then we should order one on Amazon!
