What do you do? Well, you rinse out your mouth. And, as you'd imagine a few small seeds fall out and get washed down the drain. However, if you have a drain strainer, it doesn't always work that way.
So, recently I've noticed my drain isn't draining too well, and I just chalked it up to it getting gunked up over time. To my amazement, upon closer inspection, some of those chia seeds had sprouted and began growing.
Talk about resilience. These seeds have managed to survive the drain hole hazard, managed to hang on to life despite being inundated with mouthwash (Listerine even!), toothpaste, soap, and hot water. I pulled the drain strainer out to take a picture of the sprouts and their long roots.
