Eggs to the bottle Stem Activity for Students/Teachers

Activity Subject: Pressure Aim of the experiment is to demonstrate the need for oxygen for combustion. The relation between air pressure and inner pressure

Experiment / Activity Materials: Boiled egg Glass bottle Match Paper

Experiment / Activity Security: Open Flame Alert Cloth Glove Fragile Glass Alert Fire Safety

Experimental Procedure: Let's throw away the pieces of paper that burn into the empty milk bottle. Peel the scrambled egg and cover it in the mouth of the bottle and press it down. Observe and discuss what is happening.

Conclusion As the internal pressure decreases due to combustion, the egg is pushed into the bottle under the influence of the external pressure (atmospheric pressure). Oxygen is required for the combustion process and oxygen will be tried to be taken in through the bottle mouth. But when the bottle is closed, it will be seen that the egg moves inward instead of air.
