  • GlaDOS was right, history will only remember one of you.

  • is this vid in 16bit color?

  • @TerminvsEst On top of peonatre's comment xenon is quite expensive, the balloon had £40 of the stuff in it.

  • @siderespector funny guy

    There is a reason Xenon is being used as an experimental anesthetic. Xenon can diffuse across the blood- brain barrier. People have come close to dieing from the inhalation effects. They may have died I do not know about that.

    That is why they probably did not do that experiment.

  • @periodicvideos

    I'm sure you know that you can inhale xenon to get a really deep voice(much like sulfur hexafluoride). The opposite of helium of course. That would have been a nice inclusion for this video, Pete talking with a xenon voice, much like he did with helium in the helium video.

  • That guy with the balloons is cheating! He dropped the "xenon" balloon before the air balloon so I suspect an evil conspiracy to cover up that there is no such thing as "xenon".

  • @Quintinohthree But the air inside the balloon has a higher density than the surrounding air. (Pressure in the balloon is higher than atmospheric pressure)

    Since density is a function of mass and volume, density should not be affecting the acceleration.

    I'm guessing that the balloon with air faces more air resistance due to its larger size which causes it to fall slower.

    tl;dr different aerodynamics I think.

  • @arunkumarvikram

    It's all to do with buoyancy. The bouyancy is equal to the weight of the displaced fluid, in this case the air, while the weight is equivalent to the mass. In the case of the air balloon we can disregard the air inside the balloon because it has an equal density to the surrounding air leaving only the mass of the balloon to be considered. With xenon this is not the case and we must consider the extra density contributing to the weight while the bouyancy is equal.
