Testing If You Can Blow Your Own Sail [17:06]

Hmm according to myth busters, it does work if you have a giant fan and sail, just much less effectively than just the fan. Since the sail is acting as an inefficient air redirecter, kinda like an airplane thrust reverser.

Also, using the leaf blower on a skateboard should work even better, since the air is coming in though the side instead of straight back.

i think the mythbusters result goes against the spirit of the myth. yes you “can” blow your own sail, but it’s never going to be as effective as shown in cartoons and such, or just turning the fan around like a normal air boat.
- I wonder how much more effective it would be if you had a duct behind the fan pulling in air from the sides, or maybe angled more towards the front?
  Apologies if they covered this in the video, but I can't watch it at the moment.

Is that what the kids are calling it these days?

I've heard it feels a lot more like you are blowing a sail than having your sail blown.
- I had a rib removed for THIS??!!

And this is why I fucking hate YouTube. 17 minutes of BS when they can’t be bothered to finish the opening scene, of course the answer is “nope”.

Did you ever watch Mythbusters?

No. You can't. Saved everyone time. This has been done over and over for a hundred years. Stop it.

Maybe try watching the video first
- Why would I watch a video that asks a question I already know the answer to unless I was a complete moron easily clickbaited by ass clowns making YouTube videos for a living?
  Oh...I'm so sorry if that offends you and your people.
The video explores other questions as well, not just the fan question.
People enjoy thinking about things, rather than rote memorization, so a video that makes physics understandable and fun for people who aren't masters in physics isn't so bad.
Lighten up a bit. Learning is never bad.
