Can you inflate a balloon in a bottle?

My hypothesis:

I think That you will not be able to blow the balloon up when the balloon is in the bottle but when you try it with a hole in the bottle because with the air trapped in the bottle it can not for anything more in the bottle and with the hole in the bottle all the air in the bottle will escape so there is room for the balloon.

Material:
All you need is a pair of scissors, a two 1 liter bottle, a couple of balloons, a nail and a cork.

What to do:
Get a bottle and a balloon stick the balloon on the lip of the bottle then with you finger push the balloon into the bottle, try to blow into the balloon now, will it blow up?  Now try with the hole in the bottle.

=onclusion:
Hopefully you had a bit of fun trying my experiment and found out what happened.  But if you didn't here is what happened. You will not be able to blow the balloon up when it is in the bottle. However, when you try it with a hole in the bottle all the air will have room to escape from the bottle which then allows the balloon to inflate.

The flying ping pong ball.

Today we did an experiment called the flying ping pong ball.  All you kneed is a one of two ping pong balls and a hair dryer.

We had to plug in the hair dryer. Turn on the hair dryer and point it upwards and hold it steady.  Place one of the ping pong balls on where the air is blowing out of the hair dryer. You will need to hold the hair dryer still or it will or it will fall of the side. When you have tried one ping pong ball an the hair dryer try it again but try putting a second ball on.

How it worked:
It worked because of the air pushing it up and it doesn't go way up because of the gravity holding it down as well as the air pushing it up.
