When it comes to demonstrating a product's capabilities, nothing can beat showing people something working right in front of their eyes instead of relying on presenting it on a slide or a video.
Back in 1992, Unisys product marketing manager Stephen Bean had his own method of demonstrating just how robust the company's products were to potential clients. His party piece was to pick a PC off the production line and drop it on the floor in front of them.
Remarkably, the machines remained intact. It was only after Bean had repeated the trick a few times that someone from the production line took him aside to quietly explain that although Unisys had no problem with someone dropping its machines in the interests of a quick sale, it was policy to ensure they were packed in their boxes beforehand.
Whatever the merits of Bean's approach, it didn't seem to have the desired effect. Six years later, Unisys stopped manufacturing PCs.
