Idea Exchange: Plastic bags can protect more than just your snacks

When reordering the plastic sheaths that cover our dental digital radiography sensor, I learned that a box costs more than $150. So instead of buying the sheaths, I purchased a box of 6 ½-x-3 ¼-in plastic snack bags, placed the sensor into a bag, cut a small hole in the bottom of the bag for the cord, and zipped up the bag. The sensor is safe from moisture, and I saved a lot of money.
