My looney sister believes in aliens. I’ve tried convincing her that there are no aliens in our solar system, but she just doesn’t believe me! “Prove it,” she says. I’m so tired of her talking about aliens that I just might! I sneak into the other room and grab dad’s solar system planetary teleportation device; this little machine will transport us anywhere in the solar system in the blink of an eye. The problem is that the teleporter has a 15 minute limit before it notifies the account owner (my dad) of the trip. I only have 15 minutes to prove once and for all that our solar system has no aliens if I don’t want to be caught!
