Double Jumping in Real Life!

Summary

In this thrilling video, the host embarks on a quest to replicate the double jump from video games in real life. After dismissing the feasibility of traditional methods, they construct a water rocket-powered jetpack. Through various trials and adjustments, they successfully achieve a double jump, showcasing the jetpack's power and potential. Despite some control challenges and the physical limitations of the human body, the video concludes with an impressive high jump and a near slam dunk, proving the engineering success of the project.

Takeaways

• 🎮 The script discusses the concept of 'double jumping' inspired by video games, where characters can jump impossibly high and even perform a second jump without touching the ground.
• 🚀 The challenge set by the script is to create a real-life double jump using a jetpack, which is identified as a feasible method to achieve this feat without the need for physical contact with the ground.
• 🔧 Hacksmith Industries, the company behind the project, opts for water rockets as a safer alternative to combustion-powered rockets for their jetpack, due to their short burn time and reduced risk of injury.
• 💡 The script describes the process of building a jetpack using water rockets, including the engineering and testing phases, to achieve the desired double jump effect.
• 🔬 The testing phase involves measuring thrust and impulse, and using a tracker tool to analyze the performance of the water jet engine, aiming to lift a person high enough to perform a double jump.
• 🐔 A chicken is used as a test subject to demonstrate the potential risks of the high-speed water jet, showing the force of the jet is capable of penetrating the chicken, indicating the need for safety precautions.
• 🛠️ The script details the iterative design process, including the use of lighter materials and custom parts to reduce the weight of the jetpack, making it more wearable and practical for the intended jumps.
• 👷‍♂️ Safety is a significant concern, with the team wearing protective gear and modifying the jetpack with shrouds to prevent injury during testing and jumps.
• 🤸‍♂️ Despite the challenges, the team successfully achieves a double jump and even attempts a dunk with the jetpack, showcasing the power and potential of their creation.
• 🏀 The script humorously acknowledges a failed attempt at dunking a basketball with the jetpack, attributing the failure to a lack of basketball skills rather than an engineering issue.
• 🎉 The video concludes with a successful demonstration of the jetpack's capabilities, including a high jump and a controlled landing, marking the project as a success in achieving the goal of a real-life double jump.

Q & A

What is the main challenge presented in the video script?

The main challenge is to perform a double jump, similar to those seen in video games, without touching the ground in between jumps.

Why are traditional methods like extendo dunking stilts and gas-operated turbo boots not suitable for achieving a double jump?

These methods are not suitable because they both interact with the floor, and if you're touching the floor, you're not performing a true double jump.

What is the inspiration behind the water ejecting backpack used in the script?

The inspiration comes from the water ejecting backpack 'F.L.U.D.D.' used by Mario in the game 'Super Mario Sunshine', which uses water propulsion for flight.

What is the main drawback of using water rockets for the jetpack?

The main drawback is that water rockets only burn for a short period of time, limiting the duration of the propulsion.

What was the purpose of building a bigger engine for the jetpack in the script?

The purpose was to increase the total impulse from the previous 150 Newton seconds to about 250 Newton seconds, allowing the jetpack to lift more weight and achieve greater height.

How did the script describe the initial testing of the water jet engine?

The initial testing involved using a skateboard and then building a bigger engine to achieve the desired thrust and impulse for the jetpack.

What safety concerns were addressed during the development of the jetpack?

Safety concerns included the potential for the high-pressure water jet to cause injury, the weight of the prototype, and the risk of tilting forward during use.

What modifications were made to the jetpack to improve its performance and safety?

Modifications included using lighter materials for fittings, machining custom nozzles, and adding shrouds to the jets to prevent injury from the high-pressure water stream.

How did the script describe the test with the dummy to simulate the double jump?

The test involved strapping the jetpack to a dummy and using a rope to simulate the apex of a jump, adjusting the pressure to observe the height achieved.

What was the final outcome of the double jump attempt using the jetpack?

The final outcome was successful in achieving a double jump and even a slam dunk attempt, although the latter was not completed due to a lack of basketball skill rather than an engineering issue.
