The FitWHISK is a new and innovative mixing bottle for nutritional supplements. The patented FitWHISK turbine technology uses a unique set of stationary and rotating turbines to create a continuously variable mixing action. The stationary turbines provide a barrier for the powder to hit, break, and dissolve into the liquid. The rotating turbines provide a motion that forces the liquid and powder to push up into the stationary turbines. The FitWHISK provides an effective mixing solution with an engaging visual experience. www.fitwhisk.com
