'Wovel' puts physics to work in shoveling snow

Charlotte DeVere has a pretty big driveway at her Allegheny Township home.

When it snows a lot, shoveling can become quite a task, so DeVere decided to put physics to work for her.

For at least 10 years, she's been clearing snow with a "Wovel." As the name suggests, it's a snow shovel with a wheel. Instead of lifting snow, she just pushes down on the handle, using the wheel as a fulcrum and flipping the snow out of her way.
