Air Sweeps Dust off Home Plate
Baseball umpires can throw away their whisk brooms if an automatic home-plate duster recently invented is generally adopted. When the device is placed in operation, a valve built into the plate rises and a blast of compressed air sweeps it clean off dust and dirt, as shown in the photograph below.
Why isn't this device mandatory at every ballpark? As an added bonus it will blow dirt into that uncooperative catcher's eyes - quit pulling that pitch son!
