Well, this was totally unexpected for Elon Musk and he was also seen muttering ‘Oh my f*cking god’ in his breath. Later it became really embarrassing for Elon Musk to complete his presentation in front of the shattered window because of the failed experiment.

Later Elon totally understood what made the presentation fail and he took to Twitter to explain his side. A fan wrote on Twitter answering to Elon Musk, “I know the real reason behind the window crack. It’s ok Elon, But maybe you should’ve thrown the ball of the window before you decided to hit the door with a sledgehammer.”

To which Elon Musk replied, “Yup. Sledgehammer impact on door cracked base of the glass, which is why steel ball didn’t bounce off. Should have done steel ball on the window, *then* sledgehammer the door. Next time …”

Elon Musk also posted a video in which Franz von Holzhausen was seen performing the same thing and it went pretty perfect.
