"Narrator:" "AND ONE-QUARTER OF ITS WEIGHT, 750 POUNDS," "IS FOCUSED THROUGH" "THE RELATIVELY SMALL CONTACT AREA OF EACH TIRE," "EASILY SETTING OFF..." "GETTIN' MY CAR DUSTY!" "...ANY OF THE MINES THEY CROSS." "Jamie:" "NOW, IN THE CASE OF THE HOVERCRAFT," "NOT ALL OF ITS WEIGHT" "IS CONCENTRATED INTO ONE SMALL AREA." "WELL, THAT WORKED QUITE WELL, DIDN'T IT?" "I GUESS NOW IT'S TIME FOR THE HOVERCRAFT." "Jamie:" "SO THE QUESTION HERE IS, IS THAT WEIGHT," "OR THAT DOWN-PRESSURE THAT IT'S EXERTING ON THE GROUND," "ENOUGH TO SET OFF ONE OF THESE MINES?" "MY PREDICTION IS THAT THE HOVERCRAFT" "IS GONNA MAKE IT JUST FINE." "EVEN THOUGH IT WEIGHS, FULLY LOADED WITH A PERSON," "OVER 600 POUNDS," "I DON'T SEE IT EXERTING 300 POUNDS" "DOWN ON ITS UNDERSKIRT." "IT'S JUST..." "I DON'T..." "IT'S NOT GONNA HAPPEN."

"OH, YEAH." "HERE IT COMES." "[ MOTOR DRONING ]" "OH, YEAH!" "YEAH!" "IT DIDN'T SET OFF A THING." "THAT WAS AWESOME." "YEAH!" "[ LAUGHS ]" "Narrator:" "THAT WAS SMOOTH, EXPLOSION-FREE SAILING." "OH, YEAH!" "Narrator:" "THE S-CURVE LAYOUT" "ENSURED JAMIE CROSSED A MAJORITY OF THE MINES," "BUT NOT A SINGLE ONE WENT BOOM." "YEAH!" "YOU WANNA COME BACK AROUND FOR A SECOND RUN?" "ON MY WAY." "MAYBE A LITTLE SLOWER THIS TIME." "YEAH!" "Narrator:" "DESPITE REDUCING SPEED," "GIVING THE MINES MORE TIME TO REGISTER THE PASSING HOVERCRAFT," "THE HYNEMAN GETS AWAY UNHARMED." "[ LAUGHS ] NOT A THING!" "THAT WAS BEAUTIFUL!" "YEAH!" "WELL, THERE YA HAVE IT." "WE DROVE ACROSS A MINEFIELD WITH A VEHICLE," "AND WE'RE SETTING OFF THE MINES." "THE HOVERCRAFT, NOT SO MUCH." "[ LAUGHS ] I WAS RIGHT!" "I LIKE BEING RIGHT..." "EVERY NOW AND THEN." "LOOK, IT MAY SEEM COUNTERINTUITIVE TO YOU" "THAT A 600-POUND HOVERCRAFT" "CAN'T SET OFF A MINE ENGINEERED TO GO OFF AT 300 POUNDS," "BUT THIS MYTH IS ALL ABOUT THE EXACT KIND OF PRESSURE." "A HUMAN FOOT, A CAR TIRE " "THOSE ARE POINT SOURCES OF PRESSURE." "BUT THE HOVERCRAFT" "IS DISTRIBUTING ITS WEIGHT ACROSS ITS ENTIRE FOOTPRINT," "ACROSS THE ENTIRE CUSHION OF AIR THAT IT'S RIDING ON." "THAT'S WHY IT CAN'T SET OFF OUR MINES," "AND THAT'S WHY IT IS THE PERFECT CRAFT" "FOR MAKING ITS WAY ACROSS A MINEFIELD." "Narrator:" "BUT IT STILL WEIGHS 600 POUNDS." "[ ENGINE STARTS ]" "HOW WELL DOES IT SPREAD THAT LOAD," "AND CAN A HOVERCRAFT CROSS ANY MINEFIELD" "AT ANY PRESSURE SETTING?" "NOW, IT'S THE MOMENT OF TRUTH." "OUR MINEFIELD IS SET TO AN ANTI-PERSONNEL PRESSURE." "THAT IS 35 POUNDS TO TRIGGER OUR MINES." "I'VE ALREADY WALKED IT AND SHOWN THAT I'M PLENTY TO TRIGGER IT." "OKAY, ADAM." "YOU'RE GOOD TO GO." "ALL RIGHT." "HERE WE GO," "TRAVERSING A MINEFIELD IN A HOVERCRAFT" "SET TO ANTI-PERSONNEL SETTING IN THREE, TWO..." "HERE WE GO!" "[ MOTOR DRONING ]" "¶¶" "[ ADAM LAUGHS ]" "Jamie:" "SAME THING." "NO MINE ACTION." "YEAH!" "THAT IS AWESOME!" "Narrator:" "THE MINES, SET TO GO OFF AT THE LIGHTEST FOOTSTEP," "ARE ONCE AGAIN UNMOVED." "ADAM THEN DOES HIS BEST TO LINGER WITH SEVERAL 360s." "Jamie:" "YEAH!" "CAN YOU HOLD IT ONE SPOT?" "[ LAUGHS ]" "Narrator:" "BUT THE HOVERCRAFT" "AND ITS CUSHION OF AIR DEFIES DEATH FROM BELOW." "[ MOTOR DRONING ]" "[ LAUGHS ]" "WHOO!" "AT THIS POINT, IT'S LOOKING MIGHTY GOOD FOR THIS MYTH." "BUT ARE WE DONE?" "COME ON." "YOU KNOW US." "YOU KNOW WE'RE GONNA TAKE IT TO THE MOST EXTREME PLACE WE CAN." "THAT'S WHAT WE'RE ABOUT TO DO." "SO WE'VE SET THIS TO GO OFF AT 5 POUNDS." "THE EASTER BUNNY COULD SET THIS OFF." "[ WHOOSH ]" "[ LAUGHS ]" "OKAY, HERE WE GO." "Narrator:" "IT'S THE ULTIMATE TEST FOR THIS MYTH." "THE HYNEMAN AND HOVERCRAFT" "ARE 120 TIMES HEAVIER THAN EACH MINE'S THRESHOLD." "BUT ONCE AGAIN, THEY FLOAT SERENELY ACROSS, UNHARMED." "YEAH!" "[ LAUGHING ]" "DIDN'T SET OFF A SINGLE MINE." "THAT IS BEAUTIFUL." "I LOVE IT." "Jamie:" "SO HOW DOES THIS WORK?" "WELL, THE ANSWER'S IN THE NUMBERS." "IF YOU DIVIDE THE WEIGHT OF THE HOVERCRAFT" "BY THE CONTACT AREA, YOU GET ABOUT 0.06 POUNDS" "PER SQUARE INCH OF DOWNWARD PRESSURE," "SO THERE'S NOT NEARLY ENOUGH PRESSURE PER SQUARE INCH." "WELL, I GOTTA SAY, I THINK THIS IS ABOUT AS EASY A MYTH" "TO CALL AS WE'VE EVER ENCOUNTERED." "YEAH, IT'S CONFIRMED." "TOTALLY CONFIRMED." "THE HOVERCRAFT IS THE ABSOLUTE VEHICLE OF CHOICE" "FOR TRAVERSING A MINEFIELD." "SURE IS." "I GOTTA FIGURE OUT HOW TO GET MYSELF ONE OF THESE." "[ STARTS ENGINE ]" "WHAT?" "OH, I'M SORRY."

"AND THE FIRST IS THAT THAT CONCRETE IS HEAVY," "AND IT'S GONNA ABSORB A LOT OF THE EXPLOSION." "84 POUNDS OF DYNAMITE, 185 POUNDS OF PURE MAN." "ON THE OTHER HAND," "THERE'S SOMETHING KNOWN AS "WATER HAMMER"..." "THERE WE GO." "PUSH!" "GOOD." "AND THAT'S WHAT HAPPENS IF YOU CLOSE A TAP REALLY QUICKLY." "AND IT CAN DELIVER A HYDRAULIC SHOCK TO THE PLUMBING," "WHICH CAN ACTUALLY RUPTURE IT." "[ LAUGHS ]" "THAT IS BEAUTIFUL." "NOW, THIS CONCRETE COULD DELIVER SOMETHING LIKE A WATER HAMMER" "TO THE EXTERIOR OF THE TRUCK" "AND BUST IT UP REALLY EFFICIENTLY." "THERE WE GO."

"Narrator:" "THE TRUCK WAS COMPLETELY DESTROYED." "WELL, THERE'S YOUR PROBLEM." "Narrator:" "BUT THERE IS EVIDENCE THAT THE CONCRETE" "ALTERED THE CHARACTERISTICS AND INTENSITY OF THE EXPLOSION." "THIS IS REALLY INTERESTING, JAMIE." "IN THAT FIRST BLAST, THERE WAS A SHOCK WAVE." "AND IT KNOCKED ALL THE LEGS OF OUR SHRAPNEL-CATCHERS OFF." "BUT I'M LOOKING AT THE SHRAPNEL-CATCHERS" "THAT ARE NEARBY." "THEY'RE MOSTLY INTACT." "SO I'M GONNA GO OUT ON A LIMB AND SAY THERE WAS NOT" "A SIGNIFICANT SHOCK WAVE EMANATING OUT." "IT LOOKS LIKE PROBABLY MOST OF THAT FORCE WENT UP," "AND WHAT WAS COMING OUT WAS ALL SHRAPNEL." "THIS IS INTERESTING." "UNLIKE THE CONTROL, THIS TIME," "THERE'S A HOLE IN THE GROUND WHERE THE TRUCK USED TO BE..." "WOW!" "WE MADE A CRATER." "AND A DEBRIS FIELD AT 250 FEET." "IT'S NOT NEARLY AS WIDESPREAD." "IT'S LESS THAN HALF THE SIZE OF THE CONTROL." "IT MAKES SENSE, IF YOU THINK ABOUT IT." "MOST OF THE CONCRETE SURROUNDED THE EXPLOSIVE," "MEANING THAT THE ENERGY WAS DIRECTED UP AND DOWN" "INSTEAD OF OUTWARD TOWARDS THE SHRAPNEL-CATCHERS."

"NO." "I THINK THE CALL ON THIS ONE IS PRETTY CLEAR." "IT'S BUSTED." "IT'S TOTALLY BUSTED." "¶¶" "YOU KNOW, AT THIS POINT," "WE'VE PROBABLY BLOWN UP MORE WEIRD CRAP" "THAN ANYBODY ALIVE."
