Bro why is Santa here💀💀💀💀💀💀💀

This dude blew up a balloon and then sucked it right back in. He basically just breathed back in his carbon dioxide and put on a fake voice. Nice one ☝️

Bro laughed like freddy fastbear

Sulfur hexafloride is what air duster has inside ???

You didn’t take in that much Him: that’s what she said

When I was 12 years old we got like 20 helium balloons I had a headache the next morning 😂

The guy with the low voice legit was born with that one sims 4 voice that we ALL hate.

There is no contrast of the same person.

I hate how low that man’s voice is

HE SOUNDS LIKE CRAIG

It looked like a miniature nuclear explosion

Fourth.

I thought they'd inhale the two gases at the same time and sound... well, normal

Bro reminds me of tick tock from spy kids 4

One time at a summer camp this year, on the last day, we had teams trying to explode watermelons with rubber bands. Someone from a different team came up to us with a helium balloon because his friend there had a birthday the previous day, and he still had the balloon. He inhaled the helium, and came over to us saying "you better not suck at this." It was hilarious because his voice was already a little high without the helium 😭

Bro really said: Uh uh uh!

Кто она? Как ее можно найти?

I thought that tom scott

Fredrick Fitzgerald Fazbearington the 3rd

Bros laugh sounded like Santa 💀

🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷😊

“YoU nEeD to Be a MaD SCieNtisT so huRrY uP” got me laughing hard😂

i was waiting for the guy with the green balloon to inhale some

They can do that because the gas in those balloons have different densities. Helium for example is six times lighter than air and allows sound to travel 2.5 times faster than Oxygen and as a result your voice has a higher pitch. Sulfur hexafluoride is the opposite of helium. It is six times heavier than Oxygen and if you inhale it then you will sound like Darth Vader.

That's really creepy? Are you serious?? What a sissy

He got that Santa laughter

The Hexa laughter tho 😭
