# 자전거에 프로펠러를 달면? #

I dive into my old collection of Popular Mechanics magazines and get inspired to build something! I found Ernest Winter’s air screw bicycle, so I tried to build it. He claims it is able to hit 20 miles per hour, will I be able to match his speed? How will I build the propeller? How can I power it with my feet? Will it go fast enough to fly? How does it compare to a giant fan? I go on the journey to test it and more!

( 1963년 과학잡지에 나온 어니스트의 ‘에어 스크루 자전거’, 프로펠러를 자전거에 달아 시속 20마일이 가능하다는 그의 이론을 실험해본다.)

You literally run a production house, from inventory to manufacturing, from filming to editing, it's a class apart... Loved it

( 작업실에서 직접 프로펠러 자전거를 만들며 영상도 찍고 편집도 하고.. 대단하네요..)

2. JaiRestore

I'm honestly impressed by the time and effort you put into these videos, Keep it up!

( 오래된 과학잡지 한 구탱이에 있던 자전거를 실험하려 이렇게 많은 시간과 노력을 쏟아 붇다니..)

3. Rob LeBrun

Looks like Ernest had a lot more prop speed when he started peddling.

4. Jacob Hall

This is a pretty interesting video.

( 꽤 흥미로운 과학 영상이네요..)

5. PBPB

this is better quality than netflix shows.

( 넷플릭스 보다 나은데..)

6. Thomas Elio

Fun to watch you recreate this. Helps to have the right tools of course.

( 잡지를 보며 다시 제작하는 과정이 아주 재미있습니다.)

The inclusion of the fog machines to show the airflow was awesome!

( 안개가 어떻게 흐르는지 보여준 장면이 인상적입니다.)

Dude you have a room full of the coolest tools I have seen and the fun you have making things is life inspiring.

( 작업실에 온갖 기계가 다 있는 듯.. 이런 기계들을 갖고 있는 것도 신기하지만 제대로 사용할 수 있다는 것도 놀랍네요..)

9. Native NoSmoke

Man the knowledge of engineering you have is phenomenal!

( 엔지니어라면 이 정도는 되어야..)

You gotta keep making old popular mechanics builds! This was so fun to watch.

( 이런 실험들 계속 해 주시길..!!)
