Pond Scum?

A while back I purchased some loose leaf tea that required sealed containers to put it in. So I've been washing and reusing old glass jars as they make their way through the kitchen. Normally not a big deal. The last jar however had previously held peanut butter. Turns out even after washing it by hand and the dishwasher the peanut scent persisted. So this was the obvious solution in my mind.

What you see is roughly two infusers of used tea leaves dumped into the jar with water added. After a few days it got nice and murky. The kids found this really fun to swirl around and see how long the leaves took to settle. To the best of our knowledge nothing came to life and invaded the house in this process either. Best of all, it seems like this worked in cleaning out the peanut scent and replacing it with some good old fashioned Market Spice cinnamon goodness.
