I had never been to COSI before. LOVED it! My 2 sons,14 & 15 (not mentioning their names)......13 was so eager to go & had a ball! 15 practically had to be dragged there. Turns out, he had a great time! (Mr.15 only has interests in hunting, fishing & eating!) Great experience for all. The Planetarium was decent. The phrase "in the night sky" was used way too much.
