This place is awesome and after visiting you will definitely know why it has been voted "Best Science Museum" in USA Today's 10Best Readers' Choice Awards, for three years in a row.
There is limited street parking available and they have a commercial parking garage. Normally they do offer parking validation, but I visited on New Years Eve, so they offered a flat rate of $6, which is standard for holidays and special events. But I think the rate is $6 all the time and she just made me feel special. If you plan on visiting here, you need to plan ahead. All visitors are required to make a reservation online in advance to visit COSI. You can not make it there at the counter.
There is a little plaza area out front of the museum that is very nice and has gliders, percussion instruments, a lot of flat green space.
We came here for their Noon Years Eve, which was included with admission. The place has three floors that are packed with exhibits. There are stairs or a glass elevator that you can use to go between floors. The elevator is huge but slow, so sometimes we just took the stairs to save some time.
The first floor has the gift shop (Science 2 Go), the snack bar (Atomic Cafe), phone charging stations, a huge dinosaur/prehistoric exhibit. There is also a hurricane wind machine (costs $3) to use and a stage area where they hold events like the Noon Years Eve celebration and periodically do an electrostatic demonstration with kids ( I highly recommend checking this out). The gift shop has a lot of overpriced items, as most gifts hops do, that you can purchase for a lot cheaper online. I recommend skipping it all together and spending more time in the exhibits. The dinosaur exhibit is well put together and I was amazed at what they put together.
The second floor (Level M) features the planetarium (included with admission). My littles and I did not find the movie that entertaining though. There is also a bike cable ride, which usually has a long line, a space exhibit, a hot air ballon exhibit, a balance exhibit, a cracker jack toy exhibit.
The third floor (Level 2) has a huge kids play area, Little Kidspace, with an interactive video game, a play hospital, a play farm, light bright, a water table area, and a play workshop. There is another exhibit area a cross the hall from this that is dedicated to illusions and gadgets. There is also a food decomposition exhibit, a heart rate exhibit, a weight exhibit and a very graphic fetus exhibit.
There is a 4th floor here but it does not hose any exhibits. That is where museum offices are located. There is limited benches and seating areas on each floor, so you will probably be on your feet for a while.
We spent a few hours here, but you can easily spend a half to full day exploring the place. They always have something going on so be on the look out for their special events and revolving exhibits. What sets this place even further apart from other similar places is its staff. They all were so very friendly, helpful, patient, and courteous. They also showed extreme pride in the museum, as they should.
The exhibits were well organized, and interactive. The museum was also very clean. There were a lot of people there, but the place is so huge that we did not even notice. There were not a long wait for any of the exhibits if any, with the exception of the high wire unicycle ride. I highly recommend checking out this place. It is awesome. You will definitely not be disappointed. My littles learned a lot, and did not even know it because they were having so much fun. We had to drag them out of there.
