can you get a new orchid from leaves?

[20jlr]

ok I was moving my orchids around when I was watering them 3 weeks ago and I snapped off two leaves of one of my cats right where another new leaf was comming out. So the whole to of the plant is off. I placed the "new" plant section botom in water. I grow s/h so I have a tray under to catch the water. My question is this, Will the leaf grow roots? It has not seemed to wither or soften at all, I konw you can do this with other plants but I could not find any info on orchids?
