Your Scientific Method

Did the MythBusters get it right? How would you have busted this myth differently? Share your experiment design for how you would prove/disprove this myth:

  • It seems that the assumption was that the concrete gets removed by being blasted off, when that might not be the case. Another possibility is that the concrete is removed by forcing the metal container to flex when the concrete cannot. If that is the case, then hanging the explosive in the center of the truck is the worst possible place. This is so because of the possible ways to set the container vibrating the symmetric/breathing mode is the hardest to excite in a metal ring. In other words, it's hard to make a ring expand and contract equally in all directions but pretty easy to make it squish into an oval. Point being, putting the explosives off center may have been more effective at removing the concrete coating.
  • For removing the concrete block, one thing you might have considered trying was the method used by people who take down buildings and rock walls in quarries: drill a hole in the cement and detonate the explosives in there. Granted, that is definitely beyond the scope of the myth, but it's worth considering.
