• Buoyant Balloon: Float Forward with Fluid Physics Scientific

  Sep 25, 2014 Now imagine a heliumfilled balloon floating in a car. All of the windows are rolled up and the vents are turned off. When the car accelerates, what, if anything, do you think happens to the position of the balloon? The answer may surprise you! Reproduce this classic physics scenario with your own car (or 

• Foil or Mylar Balloons FAQ Koch & Co

  All 9 inch foil balloons are designed exclusively for air inflation as they cannot hold enough helium to float. Small foil balloons are made with a valve inside the tail at the bottom of the balloon. The valve has to be opened to inflate or deflate the balloon. We suggest pushing a drinking straw gently up the stem until you feel

• Buoyancy How Things Fly

  Since the balloon itself is heavier than air, it must be filled with a large volume of something much lighter—either hot air or a very light gas, such as helium. Because the combined weight of the balloon and the gas is less than the weight of an equal volume of surrounding air, the balloon rises. This interactive experience
