Where Do Loofah Sponges Come From? This Crazy Seed Pod!

I had assumed that loofah scrubbers were some type of aquatic animal like the sea sponges, but take a look at this: You can grow them in your own garden!
Loofahs (or "luffas") are actually large fruits grown on a vine. The dried-out, cucumber-like pods are what become the fibrous sponges that are used as scrubbing pads.

Who needs loofahs from Bath & Body Works when you can harvest your own?
If your skin doesn't need any more exfoliating, you can even eat the pods before they begin to dry out!
