Tried it out with a groupon but that wasn't even worth it.  Top floor is just \"observation\" deck so the same stuff you can see by looking up when in your backyard.  Two floors have exhibits.  The vortex machine was broken.  Most of the exhibits are models or even Legos.  A few pictures and patches on the walls.  Three things worth seeing.  Meteorite exhibit is one.  Kids enjoyed the magnetic rock you can touch.  Interactive planet projector thingy is two.  Kids like making the planets bounce around.  And simulated cockpit where you could touch buttons, etc.  Overall a waste of time and money.  The \"planetarium\" might be fun and the simulators could be cool but I'm probably never going to try it based on the rest of the place being a rip off.
