ATP Science Shaker

You can make it without the spring ball sounding like you're making a Mojito at 6 a.m. at the gym or the agony of spring ball creation in your kitchen drawer resembling a slinky unravel. It's stylish, and because we know that everyone leaves a shaker with its residues a bit too long after use, our staff has confirmed that it washes readily with no lingering post-protein stink.
