and there's another one one shows how to get it inside and how to take it out

Get a peeled hard boiled egg into a glass bottle
you'll need a piece of paper + wooden matches + a glass bottle and a peeled hard boiled egg
steps :
1set the piece of paper on fire
2put it in the bottle and put the egg on neck of the bottle
notes
1egg is wiggling
2fire went out
3egg is sucked into the bottle
explanation :
the fire causes the air inside the bottle to heat up and expand rapidly ( when the molecules of the air are heated they move far away from each other ) , the expanded air leaves the bottle ( some of the heated molecules escape out past the egg that's why we see it wiggling on the top )
when the flame went out the air in the bottle cool down and the molecules of air moves closer leaving a space , the egg on top is preventing the outside air from getting inside and filling that space as a result the pressure of the air outside the bottle on the egg is bigger than the pressure of the air inside the bottle so it pushes the egg inside .
addition : to get the egg out of the bottle we do vice-versa which means we add some more air inside the bottle by exhaling ( blowing) in the bottle causes air pressure inside the bottle to rise then it becomes greater than the pressure outside the bottle wich pushes the egg out

عـــذرًا إذا كانت هنالك أية أخطاء لغوية أو إملائية
بالنسبة لـــ Addition هي عن العملية العكسية (إخراج البيضة من القارورة) إذا أحببت حذفتها أو تركتها
إذا وجدت غموضا أبــــــــلغني !

peace !!
