I my favorite way to suspend the orchids in water is tying them to disposable plastic spoons and forks (deluxe make, of course) as you see with the Cochleantes. For the Sharry Baby next to it I used a large salad fork and had to tie the heavy odontocidium bulb to an inverted net pot and Christmas light stake.
I have more examples of water culture in my Passive Hydro album. I also talked about my experience on the second page of this thread
Phalaenopsis in water culture
I hope this link works.
