Just say no to sweat stains. Build your own bladeless fan.

It has been an unusually hot summer. With a seemingly constant heat advisory in effect, my summer has been far less productive than I had originally hoped, with project after project being relegated to the fall. It has even been too sweltering to work in my garage without the aid of three fans oscillating in succession. But if you pride yourself on being a builder, not a buyer, then spend your next red-hot weekend crafting your own bladeless fan. In a recent video, Navin Khambhala demonstrates how to construct your own inexpensive bladeless fan using a bucket, a spray bottle, PVC piping, a 12V DC motor, and a 12V DC battery.
