Did Donald Duck Inhale Helium?

I'm sure most of us have sucked back a quick inhale from a helium balloon and had a good laugh. Sounding like Donald Duck or the Chipmunks is enough to make anyone crack up. What is it about helium that makes us sound so funny?

No one will disagree that helium changes your voice, but not everyone believes it is helium that causes your voice to become high-pitched. What it does is change the timbre of your voice. This has nothing to do with falling trees. Timbre is what allows you to tell the difference between the same note played at the same volume on two different instruments. It also helps you hear the different parts of speech, like vowel sounds.

You need to know how sound works to understand what happens. When you talk, air travels from your lungs up through the larynx and out of your mouth. The larynx has a pair of vocal folds which form a V-shaped slit. When the air is leaving, it hits the underside of the vocal folds and makes them vibrate. Are you still with me? This vibrating excites air molecules in your vocal tract. By moving your tongue, lips, roof of your mouth, etc. you can create recognizable sounds. So that's how sound works. Let's get back to helium.

Helium is much lighter than air. Because of this, the speed of sound is much higher in helium. When you inhale helium you increase the speed of the sound of your voice. The shape of your vocal tract doesn't change. If you increase the speed of a sound you also increase the wavelength. However, on the way to the ear the sound travels thru air again and the wavelength goes back to normal. It's not the change in frequency that gives you the squeaky voice but a change in pitch. The sound has the same frequencies but helium causes a shift in your timbre. This means the higher frequencies are getting a higher enhancement than normal so the pitch changes. The end result? You sound like a chipmunk.

Although inhaling helium is fun it's not exactly healthy. Every time you inhale pure helium, you are not inhaling oxygen. Whatever you do, never inhale helium from a high pressure tank! Besides the serious risk of lung damage, you could end up with bubbles of helium in the arteries that lead to your brain. This can lead to stroke-like symptoms and, of course, death. Still laughing? Didn't think so.

This is probably the cutest thing about growing up I've ever read, I just... Everyone grows up. No one's the exact same person they were 3 years ago, sometimes they're not even the same way they were 3 days ago. Every single is person is going to look back at their past self and cringe at something- something they said, something they did, something they didn't do. It's a sign of maturity. Everyone gets there (eventually; some earlier than others). I came back from a break around two or three months ago and wow did I feel embarrassed. I was in such an extreme scene phase when I made this account and everything was so.. yikes. My bio and albums were scattered with pictures of band members and "emo" YouTubers and I wanted to, like, burn it all (I deleted a lot of them, but the less cringey ones are still there). And my username..? Oh man my username. Not gonna be able to live this one down, that's for sure. I'm going to stay until I'm 18, if I find the time to (which I should because cyber school isn't that time consuming so). Maybe the remnants of 12 year old Kristin are the bane of my existence, but I've made some nice memories here, and I'm looking forward to making many more. (:

In other words, he's building a wall so that people will stop breaking the law.  2. He's hired many Muslims and has many Muslim friends. His ban on Muslims has recently changed, but even in its' original state, it was a temporary ban meant to combat radical Islam. Trump's Muslim policies have never had anything to do with thinking that all Muslims are bad, it's just that most terrorists are Muslim and a temporary Muslim ban would eliminate most of the terrorists coming into our country.  3. Business deals with politics, and perhaps we need someone who's not a politician? Many have become corrupt, have been found to blatantly lie to their people, have not kept their promises after being elected. If anything, the fact that Trump is successful and yet not a politician is even more of a reason to vote for him.  Honestly, I thought the whole "Trump hates Mexicans and Muslims" thing would have been over by now. It's so obvious that he doesn't hate them, all you have to do is listen to what he says.    1) Just a few issues with the wall, disregarding the purpose. Is the wall going to replace current fencing? There may be major breaches whilst the wall is under construction. Will Trump have permission to build on every inch of land the wall is to be placed upon? How do you expect Mexico to pay for it when they outright refused? The geography alone will not make it easy to build completely along the border. Do you not think the alienating Mexico will create a larger social divide between the two countries? Finally, the engineering alone behind the wall is so implausible, I don't think Trump himself realises just how difficult it will be. 2) "He has many Muslim friends" - Oh dear, the classic anti-racist comment. 'I'm not racist because I'm friends with blacks'. His current proposal is just as absurd as his original proposal. He wants to ban Muslims coming from countries with a terrorist past? (or has he changed his proposal yet again?). Let's see, that consists of almost every country in the world if you want to go back far enough. How far in the past does he want to look? He also mentioned that he wants to suspend immigration of the same people trying to enter countries with US alliance. What, does he plan on flying over and stopping Iraqis from entering the UK? That should be entertaining. This ban though... yes, you're preventing 'Muslim terrorists' from entering the US but you're also preventing 1.5 billion other Muslims from entering. That totally seems fair. Why don't you ban holiday makers from entering the US too, because 1 decided to commit murder in the past? You'll probably get a similar attacker-innocent ratio. 3) Can we stop with the whole idea that being able to run a business means you can run a country? If that were true the UK would have had Sir Alan Sugar in power years ago. He's not even an economist. He probably doesn't even know what a Current Account is. The government isn't a business. The US has a free market economy, not a command economy. Trump isn't going to be a salesman, he's going to be a Prime Minister. It's vital he knows his politics. He may have ideas that people love but he has no idea how to run a country. P.s. I really worry for America's future economy if their idea of a 'successful' businessman is someone who ends up piling on so much debt that his businesses reach bankruptcy. There are countless businessmen more successful than Trump that 90% of people haven't ever heard of. Trump loves to big himself up and so do his supporters. You're making the man sound far greater than he actually is and it's possibly going to cost you the future of your country.

The only thing you could blame Bush for is the war in Iraq, but even though Obama didn't start the war in Iraq, he ended it in the worst way possible.

Don't worry I felt the same way when getting back on this account. I had made it when I was about to turn 11. I am 15 now. Time changes a lot and I am definitely not the same person I was when starting kidzworld. I'm starting my Sophomore year after summer is over and honestly I'll probably try to stick to this website for as long as I can until they lock my account when I'm 18.
