YSK: A single piece of paper towel can double the life of your leafy greens in the fridge.

Why YSK: Because nobody likes slimy spinach, and this little trick soaks up the excess moisture that makes them turn. It's like a tiny, silent hero for your fridge, saving you money and the sad feeling of throwing out perfectly good produce. Plus, more kale for your kale smoothies, if you're into that sort of thing.
