Out of This World! Ethan Flask and Professor von Offel Take on Space Science (Mad Science)

Question: What do you get if you combine one cool teacher, one wacky scientist, and one kooky bird? Answer: A story that's out of this world. Five, four, three, two, one... Mr. Flask and the kids at Einstein Elementary are about to blast off into a super-cool study of space science. They're even going to link up with a space shuttle and ask a real astronaut real questions. (Which has got PTA president Mrs. Ratner really worried!) Meanwhile, one of Mr. Flask's lab assistants thinks he's solved a big mystery: Is Professor von Offel actually a ghost? Prescott's got the answer... but can he collect the evidence?
