Adam Savage Unrings a Bell – Unimpossible Missions

As it turns out, you CAN unring a bell. Adam Savage demonstrates how GE’s scientists, using the same scientific principles behind noise-canceling headphones, were able to prevent the sound of a ringing 20-ton bell from waking a nearby baby. Watch more here!

  1. Destructive interference aka noise cancellation aka existing for aaaages. Would be nice if I just knew what the ad was really about as I can’t order anything right? 🙂

  2. Next week on Adam sells out, we learn how flipping a light switch completes a circuit, thus turning on a light bulb!

  3. I think I may cancel my Premium Membership since it doesn’t seem to be helping Tested enough to make the content I thought I was contributing to.

  4. I don’t mind them making a bit of money for the content at all, through some extra ads… why not. What I find a bit disappointing is that these all contain the people I love to see for “serious” stuff. This ad doesn’t make me buy anything, it only helps in questioning if that Dremel wasn’t sponsored as well (which I know, it isn’t but you get the point). It’s something I don’t want to feel watching all the amazing stuff and I’m more than happy to pay more btw.

  5. The water demonstration would have been cool, if they had actually showed it working. But instead, the camera zooms in, the video slows down, and a graphic overlay shows what it’s supposed to do. The water, from what I could see, wasn’t actually doing the same thing the graphic was showing. But working or not, it’s a shame to build that test rig and then show so little of it in operation.

  6. The WETA weapons vid more than makes up for it.

    As for this video…

    ‘…and sometimes, you go back to the well’

  7. I want to know if this technology would allow you to put up an acoustic barrier. Like having half of a bar jamming out to loud music while the other half could carry on conversations, or to greatly reduce the sound profile of motorsports events for the surrounding neighborhoods.

  8. “… and yet the engineers at GE were successful in their attempt to create a quiet zone around that baby.”

    *doesn’t show this happening at all*

    WHELP i guess we’ll just have to take your word for it, Adam.

    edit: ok so i watched the video he refers to. still kinda have to take their word for it

  9. many apps were released during the African FIFA world cup to subtract the vuvuzela noise coming from the crowd by outputting the opposite waves. I can say that it was painful watching it without them.

    Like that but constantly for 2 hours. Most broadcast channels at the time also offered 5.1 where the rear speakers were ‘field/stadium noise’ so by adjusting the volume you could turn of the angry bees and still hear the commentary.
