[0:00](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle) I wonder how many breaths it would take me to fill up this incredibly long plastic bag. Do you think there's any way I can fill this whole thing up with one breath?

[0:11](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=11) I bet you I can. Stay tuned to the end to see the real answer, but let me show you the standard way of filling this up. We'll take our breaths.

[0:23](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=23) One hardly did anything.

[0:30](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=30) There's ten. I'm not even halfway there, and I'm ready to pass out.

[0:34](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=34) Is there perhaps a better way to do this?

[0:37](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=37) Let's see. Let me take all the air out of the...

[0:42](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=42) And now we're gonna use something called Bernoulli's principle.

[0:47](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=47) We're gonna blow into the bag, but we're not gonna put our mouth right on the bag.

[0:50](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=50) And what happens there is as we blow in, surrounding air is pulled in as well to the low pressure area.

[0:58](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=58) This is Bernoulli's principle. Firefighters know about this. We'll talk about that in a moment.

[1:04](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=64) So here we go, one big breath.

[1:18](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=78) Filled up the whole tube. So I said firefighters use this too.

[1:24](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=84) If you ever wanna get the air out of your room, maybe it's, uh, hot at night and it's the summer, and you don't have an air conditioner, so you're using a fan, don't put the fan right in the window.

[1:33](https://www.translate.mom/transcript/5SWd1gPQZjox/en/filling-a-long-bag-with-one-breath-using-bernoulli-s-principle?t=93) Back the fan up just a little bit, and now it'll blow air out, but will also pull the surrounding air out with it.
