BGR:

Tesla’s Cybertruck unveiling last week was one for the ages. Aside from introducing a tank of a truck that looks like it belongs in a futuristic military movie filmed in the 80s, a demo meant to highlight the Cybertruck’s armored glass didn’t go exactly as planned. As you’ve likely seen by now, two of the truck’s windows shattered immediately on impact when Tesla designer Franz von Holzhausen threw a metal sphere at them. The sphere didn’t make it into the truck, but it was embarrassing turn of events nonetheless.

Naturally, the failed demo elicited an avalanche of laughter and hilarious memes from folks online. But if we move beyond the comical aspect of the demo-gone-wrong, you might be curious as to what exactly went wrong.

Interestingly enough, Musk himself provided some insights about the shattered windows via Twitter.

I’m not a fan of Musk or that monstrosity of a so-called truck but I did feel bad for him. Having done many presentations I know how awful a failed demo can feel. But the explanation is interesting and, in hindsight, obvious.
