By the way, corals can be out of water easily up to and above an hour with very minimal issues...just don't leave them by a heavy air movement area, like in front of a fan. They will create a mucus that keeps them very moist and able to breate fine out of water. Some people(including Eric Borneman) feel it is better to leave a coral out of water for an hour rather than leave it in a bucket with a little water for an hour. It creates less chance of suffocation(using up all usable O2 from the water occurs quickly, where this will not occur out of water. This is also why Eric Borneman prefers, the damp towel method of shipping over putting it in a bag fully submerged with a limited quantity of air. I have attempted moist towel shipping before and it had very good success(opened during acclimation). If you're worried, do what Christie said and just run some water over it...zoos are very resilient.
