6. Why ?

8. WHEN THE FLAME GOES OUT - the air cools down - Molecules move closer together - A partial vacuum is created P inside < Poutside The higher pressure of the air outside the bottle pushes the egg into the bottle.

9. Is it possible to get the egg out?

10. If we blow air into the bottle around the egg…

11. P inside > P oustside The egg goes out

14. 1- The egg does not move There is a balance of forces exercised on the egg 2- The egg falls in the glass The only force being exerted on the egg is gravity The egg is in free fall

15. Thanks for your attention
