This episode of Learn Quick is supported by the Mozilla Foundation I recently watched the video by a guy called LA Beast, and in that video he learns to smash a glass using his voice alone. Immediately after watching that fantastic video, I thought to myself I want to learn that! So I know that you have to sing or produce a tone with your voice at the same frequency that the glass naturally vibrates at, when you ping it. I’ve got my eye protection, just in case this actually works. This is day one hour zero Maybe I have to sing into the glass So the reason he puts a straw in the glass is so that he can tell when it starting to vibrate with his voice because that’s when the straw starts jiggling about like that. Did you see the straw wobbling in there? I’ve tried three different glasses, but it’s not working and now I don’t know if this is a problem with my pitch or if it’s a problem with the volume more practice required on day two I decided to use an app on my phone to help me practice holding the note at the same pitch and with volume.
The phone tells me when I drift off pitch and when I dip in loudness That’s bad, I want it to be a perfectly straight line It’s a straight line so that’s good, so I’m gonna work on this at a low volume and slowly work on increasing the volume I’ve done some pretty annoying Learn Quicks in the past, but this one, this one is different This is day 3. The problem is I’m not loud enough, so we’re just gonna practice on volume now Can you see the straw jumping around? That is me holding the pitch at the right frequency and at a higher volume, but still it hasn’t broken But we’re making progress. That’s as loud, that’s as loud as I can do it. Ah, this is doing my head in. Day seven. Raising your pitch slowly until you find that the straw vibrating is easier than just trying to nail it first time for example, I come up slowly Still haven’t smashed it though Sorry We’re starting to think this is either impossible Or I just don’t have the lung power to produce the volume needed to break that I have tried every variation of wine glass in my house to no avail So I went back to LA Beast’s video and watched it again and at the start he says that the glass must be crystal.
So we nipped out, went shopping and bought these glasses and on the box it says Crystal, I don’t really know what crystal means But what I think – anyway – is that the glass will be more brittle, which is good for us. Okay, this is day… I don’t know… I don’t know what day this is Wow, can you hear that ringing after? [celebratory cheering] All right, to make it right we’ve got to do it twice. So, how to break a glass using just your voice. First of all you must wear Eye protection you’re gonna break a glass right in front of your face! Second of all, make sure you use a crystal glass. Normal glass doesn’t seem to work. You want to be able to reproduce That tone as loudly, as accurately and for as long as you can. I like to sing it right there So I put my mouth right there. Not *in* the glass and not at the bottom like that The only way to be able to sustain that note that loud for that long is to practice it took me a while That’s how you do it! Thank you very much for watching.
