The video features Cory and his friend Nate building a "slip and fly" ramp in Cory's backyard. The ramp is designed to launch people 30 feet in the air, and they aim to build a 16-foot long, 12-foot high ramp with three sections that can be adjusted to different heights. After gathering materials and designing the ramp, they begin construction, making sure to get the measurements and angles correct to avoid any safety risks.
Once the ramp is complete, they build a dock for it to sit on and use an electric winch to pull themselves up the ramp. However, they soon realize that they need more speed to get the desired effect, so they decide to use a car to pull them instead. They attach a rope to the car's wheel and use it to pull themselves up the ramp, achieving the desired speed and height.
The video ends with Cory and Nate successfully launching themselves off the ramp, with Cory reaching a height of 20-30 feet in the air. They plan to take their "slip and fly" ramp to the next level, with even bigger and more extreme stunts.
Here are the key facts extracted from the text:
1. The closest slip and fly is a 20-hour drive to Mexico.
2. The ramp is designed to be 16 feet long and 12 feet high.
3. The ramp will have three sections that can be adjusted to 8, 10, or 12 feet.
4. The builder, Nate, also built a human catapult.
5. The ramp's design is inspired by Nitro Circus and other extreme sports ramps.
6. The ramp's angle is steeper than usual, with a radius of 25 feet.
7. The builders are using an electric winch to pull the rider up the ramp.
8. The winch is attached to a rope that costs $5 per piece.
9. The ramp is built with plywood that costs $20.
10. The builders are using a zip line to pull the rider up the ramp.
11. The dock for the ramp is 6 feet long, but will be extended to 12 feet.
12. The ramp is designed to be used with a car tow, using a rope and a wheel without a tire.
13. The car used for towing is a Honda with an open differential.
14. The builders are using Ryobi tools and speakers, which are sponsored by Ryobi.
15. The Ryobi speakers can last for over 32 hours and can be connected to up to 100 speakers.
16. The car tow will pull the rider up to 30 miles per hour.
17. The builders are using a tube instead of a rope to pull the rider, for safety reasons.
18. The final launch of the ramp is successful, with the rider reaching a height of 20-30 feet.
