As cement began to leak out around the back doors, they set off the explosion and were amazed to see all the cutouts intact, with the truck's side and roof panels peeling away from the frame.
When they were reset to anti-personnel mode, Adam was unable to set them off as well; Jamie then made one last run with the triggers at 5 pounds (2.3 kg) and completed it safely.
After Adam inspected the interior to verify that it was in good condition, they sealed the release valves and attached a vacuum gauge and temperature sensors.
The vacuum readings peaked at 27 inches of mercury (91 kPa) as the car cooled to 100 °F (38 °C), but no collapse had occurred after 60 minutes and they ended the test at that point.
Again, the car remained intact after 60 minutes, so they vented it to the atmosphere and dropped a 3,200-pound (1,500 kg) concrete block on it from 30 feet (9.1 m) to investigate the effect of physical damage.
When they replaced the flame rig with a 3-foot (0.91 m) long sword forge running at 2,100 °F (1,150 °C) and fired a fully prepared shrimp directly through it, they found that its temperature still had not increased significantly.
The same result occurred with a 12-foot (3.7 m) long forge, prompting them to declare the myth busted as the shrimp did not have enough time to absorb the heat needed for cooking.
Before visiting the range, Adam and Jamie had run a tomato through an industrial juicer at the shop and obtained a 62% juice yield based on its original weight.
To investigate the use of larger quantities of explosive, they set up a new trial at a quarry pond, placing 20 pounds (9.1 kg) of TNT underwater at a depth of 10 feet (3.0 m).
They deemed the myth plausible, and Jamie noted that the use of the small box allowed the shock wave from the explosion to reflect back and forth from the walls, repeatedly striking the tomato and more effectively delivering energy to it.
They deemed the myth busted, with Jamie commenting that a plate thick enough to withstand the blast would be heavy enough to crush the car simply by being dropped on it.
They set up their equipment on Treasure Island, placing the cups (total area 1,880 square inches (1.21 m2)) on the hood, roof, and trunk of a 2,800-pound (1,300 kg) car.
When they started the vacuum and began to lift the frame, the car fell off due to excessive buckling of the hood that caused its cups to pop loose.
A second test with a different arrangement of the cups also failed; after replacing the hood with a flat piece of sheet steel to eliminate the buckling, they were able to lift the car 1 inch (2.5 cm) off the ground before it fell.
Returning to the shop, they decided to replace the suction cups with three large plywood boxes, contoured to match the car's shape and fitted with rubber gaskets for a tight seal.
This time, the car remained attached to the boxes even while being lifted to the crane's maximum height, after which Adam and Jamie shut off the vacuum cleaner's power.
Adam created an appropriately-weighted safe mockup for testing, with a switch on the blade to measure total contact time (with 0.75 seconds taken as the minimum needed for a kill).
Thinking that a ricochet might affect the results, they set up a concrete paving stone to bounce the bullet into a cardboard target and shot at it from different angles (45, 25, and 15 degrees).
A fourth trial without the gloves gave a time of 2 seconds, due to the force of his punches being concentrated over the smaller area of his bare knuckles.
Adam, Jamie, and the Build Team (Tory Belleci, Kari Byron, and Grant Imahara) gather to reminisce about their time working together.
The passenger results were similar to the first trial (34 g head, 45 g body); however, Buster's readings decreased to survivable levels of 41 g and 55 g, and he remained in his seat even though most of the wrappings broke in different places.
Adam and Jamie noted that the tape around Buster held him so firmly in place that he experienced the same deceleration as the entire car, leading to his fatal result.
