I think a must-have for any shower is a loofah, which if you don't know is kind of like a rough sponge that you use to help exfoliate and scrub off any dead skin cells. And according to Mark's Daily Apple, you don't need to buy one of those expensive loofahs at the body shop -- you can easily make your own. Here's how:

• Grow a loofah (also called Luffa) in your backyard -- it's actually a vegetable that looks a lot like a cucumber
• Pick it once it's ripened
• Peel off the outer skin
• 'Milk' it, to get all the moisture and fleshy bits out of the middle. Save the seeds to plant them next season
  
• And that's it!

I had no idea that a loofah was a vegetable. Did you?
