Almost six minutes. This fellow has watched Mythbusters too many times: "First, I'm gonna tell you what I'm gonna show you; Then I'm gonna show you what I have to show you; Then I'm gonna tell you what I just showed you." All he needs is a commercial between segments.Mind you, it's a nice effect and I'm glad he showed me.
