Here is a nifty gift just in time for Christmas. A replacement for the fly swatter. According to the accompanying video you can blast flies with air propelled salt.

Flies walking on your food? Not a problem. With the bug salt gun you can blast flies with one shot. Salt your food and pepper it with bug parts all in one shot. What’s not to like?
