Balloon In A Bottle

Can you blow up a balloon in a bottle?  This experiment answers that question. You can also use this science experiment to trick and amaze people.

Materials:

1 Bottle

1 Balloon

1 Nail

Procedure:

1. Strap the balloon on to the mouth of the bottle so that the rest of the balloon is inside the bottle.
2. Now blow into the balloon. It should be quite difficult.
3. Stick the nail into the bottle anywhere around the sides.
4. Now blow up the balloon. It should be much easier.
5. Now put your finger onto the hole. You should notice that the balloon shrinks.

Why it happens:

Once you seal the bottle with the balloon the air particles are trapped in it needing lot’s of space. When you blow into the balloon they take back the space. But when you put the hole in it they have more space to go. Once you put your finger on the hole the need the space making the balloon shrink.

So the answer depends on if you’ve got a hole in it or not. Remember there are many more fun and exciting experiments like this and lots of them just use things that you can find around the house.
