Inside the giant nose was good - the slime and snot did look very realistic!
I liked the smell exhibit where you had to identify smells - it's good because you learn to identify the smells of the body in a funny and interesting way.
The bogeys game was my favourite - you had to shoot dirt balls up the giant nose and sometimes it was sneeze it back at you. I liked it because you understood what it was showing you right away and it was hands on.
