...you MUST go see Hubble 3D. Trust me.

It was probably the most amazing film I've ever seen, and I'm not even a space geek. I don't know how to describe the impact that this movie had on me. It was only a 45-minute film, but I left the theater feeling like I had been part of something historical, like I'd been out there in space with the astronauts on their spacewalk. It was so.... real.
If, at like our theater, the movie only plays during the day, check your kid out of school for "an appointment" so you can take them to see it. They'll think you're super cool for letting them watch a movie instead of sit in class, and it will be far more educational than anything they'd do in the classroom.
