Electric milk frother
Oh, I'm sorry, do you run an illegal, underground coffee shop operating in your home? Then by all means buy yourself a handheld milk frother. Your neighbors will appreciate it! But if you think that while you're trying to get to work on time on a Monday morning, you're going to take more than five seconds to quickly froth some milk in your coffee-filled Hydro Flask, you're wrong.
Yes, it's super fun to spin anything around and shout, "Wheeee!" But you don't need to spend money on drying your lettuce in a fun way. I recommend sitting on an office chair and spinning yourself around. More fun and infinitely cheaper.
