Does farting make you weigh more or less?!?! Place your guess and give me feedback too-

I’ve been an Architect for 20 years and have loved everything about science my entire life. I had NEVER had someone explain why helium makes your voice higher! I found myself smiling at that “Eureka” moment. My 16 year old son loves everything you’ve ever done and I’m glued to my screen every video as well. Keep up your enthusiasm; it’s addictive.

A simple explanation: Sound, is air vibrations that your eardrums hear. Sound is slower than the speed of light, and if anything exceeds the speed of sound, it creates a sonic boom. Your vocal chords create vibrations that create air vibrations to bump into molecules. Helium makes your vocal chords easier to move, making it high pitch. Sulfur hexafluoride makes the vocal chords move slower, making it lower pitched.

I don’t think this is correct. Your vocal cords vibrate at the same frequency for all 3 gasses. The reason your voice is higher with helium is because the speed of sound is faster through that gas due to its lower density (and similar compressibility) than air. This changes the resonances of your vocal tract by making it more responsive to high-frequency sounds, so the low parts of your voice are still there, they’re just not as prevalent as the higher pitch ones with the helium. Someone please correct me if I’m wrong though, this is just what was taught to me in physics.

Does that mean that speaking with the sulfur gas would be harder? And speaking with the helium gas would be even easier than talking normally? Someone answer lol

“Teaching HS Physics is my dream job” ..... I am failing Physics right now, not because I don’t like it but because my teacher *sigh* just isn’t the best. I would absolutely just love it if you were my Physics teacher. If that could happen in some alternate universe, you would make me the happiest person ever. Your videos are the reason I’m not giving up on Physics. Seeing your videos and passion about how the world works is super inspiring and exciting:). So yes. Please become a Physics teacher. You would change so so so many students lives. Best of wishes as you pursue getting certified and all that:).
