Have you seen this viral demo video from NeverWet? This stuff is so water-repellant that you can spray it inside a cardboard box and turn the box into an ice chest. That’s a remarkable product (and having a remarkable product is the first step to making a fantastic demo video).
With over 6.2 million views, this video is proof that if your stuff is really that great, you don’t need persuasive actors, a studio to shoot it in, or a film degree. The NeverWet demonstrators are just regular employees, the setting is just wherever they can make a mess, and the video quality is fairly average.
In fact, because this video has so few frills, it seems more authentic. It lets the product speak for itself — which, after all, is what a demonstration is supposed to be all about.
