It's even harder when your engine is a 0.7-horsepower person. But one team of engineering students is trying to do just that.

1. Ok ok I'm impressed!
2. lol xD WTF
3. so, what happens if the guy gets tired?
4. Its unstable because the fan blades are below center mass. They are doing this to use the ground effect for what it's worth. This is why they don't continue to climb once they reach the altitude where this effect diminishes. To go higher, they would need a fair bit more energy. I would love to see where they are at in a few years, but it appears that one person is not enough to break through using this (high end) equipment.
5. add more rotar tilt dumb dumbs
6. i mean i'm not an engineer but isn't fishing line lighter and stronger than most string. I think with the volume of string they are using it could take off half a pound maybe.
7. How is that thing 80 pounds that's like the weight of my little sister
8. I want one powered by hamsters.
9. Awesome🙀🇨🇦
10. They should have a kid do it.
11. Maybe use gyroscopes
12. rice is a challenge
13. fake rice bro
14. Foi como se tivesse saido de um sonho
15. why not use chains instead of unspooling a string
16. Congratulations guys!! such amazing work. The kind of videos that make me fall in love with mechanical engineering ❤
17. Holy shit, Wow, that actually worked OO
18. and now trying with Rosie O'DONNELL
19. superb job keep going
20. Good job nice
