One of the highlights of the new Tesla Cybertruck unveiling was when Elon Musk cracked the two windows after tossing a metal ball towards the car.

According to Elon Musk, the windows were made using “Armor Glass” which would make it hard to crack but it instantly cracks when the metal balls were tossed towards it. That ended up being the joke of the day for many with many people suggesting that Tesla do a test first before performing such a stunt in public.

Well, not too long after the unveiling, Tesla Musk released a video showing them testing on the same prototype and it did not crack or scratch the glass.

However, he also acknowledges that there are still some improvements that they need to make before the truck heads into production.
