How do you open a empty spray can?

To open an empty spray can, first ensure it is completely empty and safe to handle. Use a can opener designed for this purpose, or carefully use a flathead screwdriver to pry off the top, taking care to wear safety goggles and gloves to protect against sharp edges. If using a screwdriver, apply gentle pressure around the rim to avoid damaging the can further. Always prioritize safety and dispose of the can responsibly according to local regulations.
