What happens when you place a water balloon on the mouth of a bottle with a flame burning inside? Watch and learn as we experiment together. Explore concepts such as atmospheric pressure, and combustion chemistry by manipulating gases and air. By discovering what establishes a scientific experiment, you will achieve comprehension on many levels while you prepare for more advanced topics.

Could I create a concentric magnetic field capable of producing electrical displacement if I place a magnetic ball that is place inside of another ball that is place inside of another ball and so on up to the 12 times: that when I start to spin the outside ball first then the one inside should spin in the opposite direction and so on: in the end you have a copper coil surrounding the 12 magnets and a magnet housing over the copper winding. This is a working theory I just see it as our solar system using magnetic fields that create electrical displacements to hold our planets in position and once in a while we see it as lighting because the magnetic field is so great it has to discharge into our magnetosphere.
I understand why the balloon is initially pushed outward. I don't understand the sudden sucking action that pulls the balloon inward. Why and how does the direction of the pressure change so fast?
Its all about equal pressures. As long as the pressure inside equals outside, nothing happens. Once the pressure outside is greater (there are fewer particles inside moving slower now) than the inside it is PUSHED in. Works well with a cider jug and a peeled hard boiled egg, too. Kids love it!
Once the fire goes out, the air inside the bottle cools. As it cools, the pressure inside the bottle drops. The air outside the bottle is at normal atmospheric pressure and is no longer balanced by the air in the bottle pushing out, so the balloon is pushed inside the bottle.
