"Gentle touching"? Maybe, but I wouldn't want to find out on one of my corals. However, I do have a short spine sea urchin that would make a great "hands-on" exhibit. I also have a lot of stuff that I could make available. I don't consider myself an "expert" per say but I am very knowledgeable and could provide him with books from my extensive library as well as information on-line.

Feel free to PM me for further details. Also, I live in Lago Vista and my wife is a 6th grade science teacher and has used my stuff for her class as well. I have been keeping aquariums for over 40 years and saltwater for over 20 years.
