You will need:

Method:
1. chek the egg will sit firmly in the
neck of the bottle
2. tear the paper into stripes and put
them into the bottle
3. light the paper by dropping a
berning match into the bottle
4. Quickly sit the egg in the neck of
the bottle you will see the egg
being sucked into the bottle with a
gurgle and a pop
How it works
as the paper berns it uses up all the
oxygen in the air the egg has sealed
the neck of the bottle so no more air
can get inside this reduces the air
pressure inside the bottel and the
egg is sucked in in fact the outside air
pressa pushes the egg into the bottle
