Stay cool, be cool: How to make your own “blade-less” fan

[This guy has found a cost-effective way to stay cool this summer/YouTube]

When the blade-less fan was introduced to the masses a few years ago, heat sufferers rejoiced. Such a practical and well-designed device seemed like a no-brainer when it came to escaping the heat.

Minus one thing: the price tag.

Well, thanks to one clever maker on YouTube, a blade-less fan is entirely feasible as a DIY project.

The end result apparently works 15 times more efficiently than a normal fan and looks surprisingly polished, considering the contraption is made up of a flowerpot and a water jug.

In his instructional video, Rulof Maker demonstrates how to put the pieces together. He uses a grinder to slice up the bottom of a water cooler jug. He then inserts a large vase inside and tops it with a Plexiglas cap and a scrap piece of plastic from the jug, which fits inside the rim of the plant vase.

In order to blow the air inside the device, he adds a smaller plastic vase from which he trims the top off. Using wood boards, he secures a microwave fan inside the smaller vase. Cutting a circular hole on the side of the water jug, he then secures the smaller fan vase with glue.

At the end of the video, Rulof explains how the air flows as a result of the Venturi Effect.

Brings a whole new meaning to the word “chill”.
