and when he can survive, you gotta use enough dynamite to vaporize him!

actually if you surround him with simultaneous dynamite he will survive like in the Bugs Bunny cartoons, it's an old rodeo trick

"In the late 60s, Hopper made Bomb Drop, a performance piece captured on film in which he sits in a circle of 20 sticks of dynamite and blows himself up. "When I was a kid I saw this rodeo in Dodge City, Kansas," he says, "this guy calling himself the Human Stick of Dynamite. He got inside this dynamite ring, waves to the audience, then an assistant blew him up, big explosion, then he gets up, waves to the audience and that's the thing. I wanted to start Easy Rider that way. I wanted that to be Captain America, Peter Fonda being the guy who gets blown up, and me being the assistant who does the plunger." Given the well-documented animosity between the two, the notion of Hopper blowing up Fonda at the beginning of the film seems fitting - but in the end they ran out of money and abandoned the idea.

Hopper finally got to do the human dynamite thing in the middle of a speedway track in Texas. He still finds this very funny. "This is in the middle of a race," he says. "So that's me just before, kneeling, trying to get the charges together because if you put 20 charges of dynamite in a circle they won't blow in on themselves: there's a vacuum. If three don't go off, you're sucked out and killed. However, it worked and we did it.""
