Egg in bottle??????? please help?

Question

hey people i am homeschooled and am doing a science exsperiment. My exsperiment is that when i burn a piece of papper and put a big egg on top of the bottle it will suck it in. So i need some help.

Where can i do research of past projects similar to this one?

In your opion what should my hypothisis be. I think it should be wheather or not the size of the piece of paper or size of the bottle effects it. So if you could help my out with those two things that would be great

Answer 1

When you burn paper,the combustion products get hot,expand,some air escapes. Then you keep the egg on the mouth, when cool down, a partial vacuum is created inside the bottle.This causes the egg to stuck on the bottle mouth.

Bigger the paper,more hot , more air escape.
