Plant identity question

Plant identity question

The digital camera isn't charged, but I have a question about a plant. My friend just gave me several pieces of this and she said it spreads like wildfire. There are three big pieces and tons of babies in the soil. The leaves are light green and very waxey and thick. They are also wide and have a ruffled edge. My friend said that you have to "pick off" the ruffled edge because you'll have plant babies up the wazoo. In fact, it looks a lot like this: but, I have no flowers on mine and the leaves aren't dark around the edges. Any ideas of what this is? The site I found that picture on says it's an air plant?!?!?
