Tesla unveiled its new Cybertruck during a live demonstration in Los Angeles on Thursday (November 21), but things didn't go as planned while showing off the Cybertruck's armored glass windows. 

CEO Elon Musk claimed the car was bulletproof against a 9mm handgun, but an audible gasp was heard in the arena when Tesla's chief designer Franz Von Holzhausen shattered the windows by throwing a metal ball at them. Musk was visibly caught off guard, exclaiming, "Oh my f*cking God. Well, maybe that was a little too hard." Von Holzhausen threw the ball again, shattering the glass. 

Musk then added, "We threw wrenches, we threw everything even literally the kitchen sink at the glass and it didn’t break. For some weird reason, it broke now. I don’t know why. We will fix it in post."
