Can a balloon pop when in cold water?

Yes, a balloon can pop when exposed to cold water. The decrease in temperature causes the air inside the balloon to contract, creating more pressure on the balloon walls which can lead to it bursting.


Can a lead balloon float?

No... it wouldn't even survive the conditions of the upper atmosphere, unless it was a very tough balloon.. even if it could I'm assuming eventually the atmosphere would reduce to a point where it was as dense as helium or hydrogen (the gas I'm assuming would make your balloon float) and your balloon would stop anyway at a maximum altitude. Either way.. after that, the balloon would have to break away from Earth's gravity (not easy) and then somehow cover 382500km or so to get to the Moon itself..


Explains why a balloon bulges on one end when you pinch the other end?

The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.


Why does your hair stand on end when rubbed with a balloon?

Rubbing a balloon against your hair creates a build-up of static electricity on the surface of the balloon, which then applies an opposite charge to your hair. This causes your hair strands, which are similarly charged, to repel each other and stand on end.


How do you deflate a balloon by using a lighter?

The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.
