Christopher Hendon researches coffee flavor profiles using electrical currents to improve brewing consistency and reduce waste.
It's simple: Spritz the broom with a cleaner before sweeping. When I asked her why, she shrugged and said, "It helps with the hair." Turns out, the reason it works has less to do with the hair itself and more to do with static electricity. Pet fur picks up static charges from rubbing against carpets, furniture, and fabric (or maybe that perpetually squashed dog bed). That's why it's so stubborn to sweep up.
Research conducted by Joshua Mendez Harper and Christopher Hendon found that adding a splash of water to espresso beans during grinding leads to a 10 to 15% increase in coffee concentration.
