This seeded soap bar from UK-based cosmetic company Lush is as organic as it gets – some of its the ingredients are so natural, they can actually sprout plants in your shower!

The ‘Wiccy Magic Muscles’ massage bar produced by the company contains several aduki beans, which are obviously still alive and able to germinate. So when customers use the bar, and some of the beans fall away from it, they sometimes get lodged in nooks and crannies of the shower where they get enough water to start sprouting little shoots.

Lots of users have been tweeting about finding tiny plants growing in their shower ever since they started using the soap. “One of the coffee beans from my Lush massage bar fell into the sink and a PLANT GREW FROM IT,” one woman tweeted.

“PSA: When using a lush bar with beans in it, and you don’t use that shower for a week this is what happens,” posted another woman, along with a picture of a tiny shoot coming out of her bathtub’s drain hole.

One Twitter user gave a rather detailed explanation of how the bar managed to produce living organic matter in her bathroom. “A few weeks ago my best friend bought me this exact massage bar from Lush,” she wrote. “I stopped using it after a while and the beans started falling off. Not thinking anything of this, I just kept kicking the leftover beans down the drain because I’m lazy and didn’t feel like picking them up. Long story short, I now have a little friend to keep me company when I shower.”

Aduki beans, which are apparently popular in Japanese and Chinese cuisine, are extremely easy to sprout. “We use organic aduki beans to create a texture in the massage bar, so that you’ve got small bead like shapes to massage the muscles,” explained Helen Ambrosen, Lush co-founder and product inventor, speaking to Buzzfeed. “In order for the beans to germinate they must be left in the shower for a few days. The results you get just goes to show how fresh the ingredients really are.”

The shoots can eventually reach a height of 18 to 25 cm, so you can pretty much grow an indoor garden in your bathroom in no time at all. But as awesome as that sounds, it turns out that the Wiccy bar isn’t supposed to be used in the shower at all. According to Lush’s instructions, users need to “glide the massage bar directly over dry skin; it will melt upon contact,” like a body lotion. Obviously, no one was paying attention.
