Now for a completely gratuitous 1 explosion underground. In three, two, one. Well, that was a nice little thud.
B was for bomb range. A was for audit 2. N was for nothing. (Fire!) And G was for grenade. Put them together and what do you get? (Fire!) And the bangs continue right now.
Alright, now I know all of this looks like a lot of automotive junk, but it is actually what’s left over from a car we explode.
So I’m guessing V is for vehicle.
Exactly. Now we have probably totaled around 130 vehicles on this show. A lot of them we’ve crashed. Some we’ve destroyed with the rocket slide of New Mexico Tech. But a lot of them we’ve blown up.
So we roll the montage.
Indeed we shall.
Next up is W, a letter that’s all about H2O. Water and explosives are a particularly good mix for Mythbusters for two reasons. First, water and air have very different properties. For example, water is incompressible. It’s denser 3 than air. It’s more conductive. And all of this means that explosions travel differently through water than they do through air.
Indeed. By being incompressible, (Go for it.) water is a great way to help crack a safe.
