Storyboard Text

  • Hmmmm...... Why don't I got get balloons for my brothers birthday!! I will get helium balloons!!
  • hi! yes it is possible! here you go!
  • Hi, is it possible to buy a few balloons for a birthday?
  • (Pretending their deflating)
  • What?!!? Why are they deflating?? One second I am looking for my keys and the next the balloons are deflating.
  • Excuse mam, but your balloons are perfectly fine.
  • Excuse me, but is it possible that you didn't blow the balloons up all the way?
  • When helium is warm, its molecules are loose and free to move around. They have more energy. Since the density of these molecules is lighter than the air, your helium balloon floats.
  • However, when helium is cooled, those freely moving molecules begin to be not-so-free. They start to lose energy. They’ll slow down and condense as the temperature drops.When this happens, the volume inside the balloon is decreased. The helium molecules are no longer expanding outward against the shell of the balloon, but are now densely packed together toward the center, causing the balloon to shrivel and sink.
  • Happy Birthday!!! I got you some helium balloons, hope you like them!!
  • OMG! Thank you so much, they're so cool, i really appreciate them!!
