Unfortunately (when I went) not all the touch screens were calibrated or it wouldn't register the touch of my hand. Apart from that tiny blip I think it was a great experience and more exhibits should be created in this way!
I think it helps all are brains and stuff(I am trying not to be wierd).
I really enjoyed walking round the Cocoon i have to say it
teaches you a lot because at frist i did"nt know what a Cocoon was!.
I also enjoyed stuff that you can put on the NaturePlus card.
What I like best was the ability to copy the information you liked best on your nature plus card...
because, seriously, no one can remember everything he saw in the cocoon.
