Testing A Helium Football! | MythBusters | Season 4 Episode 7 | Full Episode

Adam and Jamie test the myth that footballs filled with helium will fly further and hang longer than ones filled with regulated air.

Using science as a tool, Hollywood special effects experts attempt to debunk rumours, urban legends and popular myths that have captivated the minds of many individuals.

I haven't seen these episodes in more than 16 years. I used to watch mythbusters as a kid every weekday evening. I had such a crush on Kari lol. It's great to be able to watch them in english (I watched a dubbed version then) and this show is even better than I remembered. I'm still very sad Grant's gone, but he is forever immortalized by this show.

Yikes, that pig jaw rig is gnarly. But then their most disgusting one remains the imploded "meat man" squeezed into the diving helmet lol

I kinda wish they had a third one filled with Sulfer-hexoflouride. It's about as many times as dense as air as air is as dense as helium.

The kick-machine was my first quess before the action. And yeah, the physics says itself that the helium myth is only a myth :)

I'm shocked they didn't already have such basic over the counter scale. Great show!

Loved this show, but in fairness to science, 1) the reason Helium makes a higher pitch voice than air is not directly related to its speed of sound, and 2) the fact that the speed of sound is higher in Helium than in air is not because of its lower density. In fact, the speed of sound is many times times faster in a metal than in Helium. Rather, I would make an informed guess and say that your vocal chord's resonant frequencies are higher in a less dense medium (meaning they will flap faster more easily). Once the sound is produced at the source at a higher pitch, your chest and head cavities WILL resonate at higher frequencies because of the higher speed of sound in the filler medium.

18:45 "extremly senstive scales" goes only to 0.1g
me who has scales at work that goes 0.001g "yeah about that"

So, the eiffel tower has a square base of 15.625 (125m per size), 330m tall and weighs around 10.100.000kg.
If we are going to make a cilinder, the smallest possible base that it can have is the square diagonal
d² = 125² + 125² => d = 176 (radius is 88)
The cilinder total volume would be:
pi * 88² * 330 = 8.024.332 m³
Since each cubic meter weighs about 1.3kg the total weight is:
10.431.632kg

It is actually true, eiffell tower needs protein for some gains

I love how they portray the scale that they bought as if it was super super accurate because it measures up to a tenth of a gram... In Europe you wouldnt even have to go to any specialized store for that... maybe if you want more than 3 decimal digits.

5:06 What a weird coincidence, it was just earlier today that I heard of the movie _White Men Can't Jump_ for the first time!

[JGPlunder]

"It blew its teeth out!" What did you expect? Lol

[alanrose]

A heavier gas would have made a ball point, MORE MOMENTUM.

[G-SUS]

I loved how anticlimactic the phrase ~"back at nasa, they test helium footballs" 🤣

16:36 Kari’s strut 😂 Geez she’s wonderful

18:50 If a ball filled with air weighs 3.2 grams more it's not because you put 3.2 grams of air in it (unless you're doing it in a vacuum chamber). Filling it with air increases it's volume, and thus buoyancy, and thus if the air inside wasn't pressurized, the scale should show no change in weight. If there is a measurable change, it would have to be because pressurized air has higher density than the atmosphere outside.
