This is a video of the Slow Mo Guys destroying an old iMac with a combustion tube blast traveling at over 4,000 miles per hour. What the hell's a combustion tube? I'm not sure, but from what I've gathered they're used for destroying old computers. I want to stand in front of one and see what it can do to my belly.
Keep going for the video.
Thanks again to BinkleBottum, who wants to put a weather balloon over the end of that tube and see what happens.
