can you grow roots from nothing?

can you grow roots from nothing?

My beautiful pepper plant that I'm so proud of (and posted about yesterday) fell over today in the wind (it's in a container), and a huge branch with 4 peppers (two of which were huge!) was on it. My brother said that there is some sort of product you can get that makes roots grow from something like this, but I can't seem to find anything online. Any ideas? Right now I just stuck it in the soil.
I am newwwww.
