COSI After Dark

I went to COSI last week which was fun.  There were lots of interesting exhibits like the drum that played your heartbeart. There was also a bunch of antique stuff like recording equipment and a jukebox and some old bicycles.  The voice-changing thing was pretty cool too.  One of the cooler things there was the electrostatic ball which you could touch then shock people with.  Overall, COSI was very fun and a learning experience.
