A former NASA engineer and two YouTube users teamed up to throw a car from 150 feet high onto the "world's strongest" trampoline.

Scientist Mark Rober spent six months planning this stunt, and finally made a steel trampoline weighing 2 tons with a Kevlar cushion and 144 garage doors. spring.

In the video of the fall, the white vehicle can be seen falling quickly and making a loud noise, hitting an oversized object-but it clearly remained intact.

Former NASA engineer Mark Rober and two Australian YouTube anchors behind the channel How Ridiculous dropped the car from 150 feet onto a two-ton steel trampoline in a new stunt

During the impressive fall, the car bounced off the Kevlar mat (pictured) and hit some of the 144 garage door springs

When the car fell from 150 feet (44m), it hit the mat slightly off center and bounced once.  

When it descended for the second time, the car rotated and hit the side of the oversized trampoline, causing the vehicle to spin and fall from the side.

Despite rigorous testing of the vehicle's durability, it managed to land the wheels only a few inches from the fence.

The main shell of the car is basically intact, the bumper and the metal plate under the car are missing, and the headlights are also smashed.  

YouTubers (how ridiculous in the picture) couldn’t help but smile while watching stunts

Then the YouTuber will check the trampoline to see if their incredible stunts have caused any damage. 

They found that one of the garage door clips had been bent, but in general, their work survived the next challenge-a boat.

When they stood under the trampoline, one of the YouTube users said: "This is where it deforms and will not return to its original shape [garage door spring].

'We have some doing this. Oh, look at this [Kevlar Net]! This is the curved one that is an inch of Iron Man. The car must have come down and hit this.

Everyone was impressed by this stunt, which made Mr. Rober feel at ease. Before the car fell, he said, "This is of course the most stressful time since I made a video in 10 years." 

Mr. Rober worked on the Curiosity rover during his work at NASA and now runs his own YouTube channel. After How Ridiculous challenged him in one of their videos, he participated in the project.

As early as September 2019, the two Australian YouTube anchors living in Perth filmed themselves falling a 90 kg Atlas rock from a height, but this destroyed the trampoline.

Then they sent a request to Mr. Rober and asked them to work with them to figure out a way to make a stronger and larger trampoline for dropping heavy objects.

Then he started brainstorming ideas with his "friend Josh", who "do some mathematical operations and run the plan through CAD and dynamic analysis."

Mr. Rob explained: “Finally we finalized a design and sent the construction plan to a friend of them who lives near the tower. After a few months, all that was left to do was walk to Australia and sign in with these people.

Then the video showed the team checking the progress of the project in the workshop, and then Mr. Rober picked up the Kevlar cushion.

He explained: “The cushion is made of Kevlar, which is the same material used to make bulletproof vests. The only way to cut it into the correct shape is with an angle grinder.”

As for other materials, Mr. Rob said: “Garage door springs can support about 450 pounds, and we have about 144.”

The team spent seven hours assembling the trampoline on site, and they worked overnight to complete the construction. 

In the latest video, Mr. Rober also explained why he likes to participate in this project so much and told the audience that it is great to be able to use his work skills.

In addition to working at NASA, Mr. Rober said that until six months ago, he worked on Apple’s special project team for four years.

During this time, he used computer programs such as CAD to calculate how things would happen before completion-a key skill for the car drop project. 

For the latest video, these people decided to record 10 drops from items such as bowling balls, watermelons, cars, and boats.
