CBSE Book Class 8 Science Activity Egg Pops Into a Bottle

 FORCE AND PRESSURE

What's oval and wears a shellsuit? An EGG, of course! For Kushal as long as it was only a riddle on eggs it was fine. He did not like eating them at all! Do you want  to know what he did to the boiled egg that his mother gave him to eat? One day, Kushal's mother gave him a boiled egg for breakfast.

“I will eat the breakfast in my room, ma”, said Kushal as he carried the plate to his room. 

“You must eat it and no tricks today” shouted mother from the Kitchen.A little while later mother heard a “pop” sound from Kushal's room. She went in to find out. 

“What happened, what was that sound?” enquired mother.

“Nothing, ma”, said Kushal trying to hide something behind his back. 

“What are you trying to hide? Show me at once”, ordered mother. Mother was shocked to see the boiled  egg inside a bottle. She took the bottle from Kushal and tried to take out the egg. But she couldn't. So, you  have been upto your tricks again. How did you manage to do this? Kushal meanwhile could not stop giggling. How naughty he was! He explained to his mother about how the egg went inside the bottle. You too can try it, but be careful while using a matchstick.

You will need: 

A boiled egg, empty milk bottle some paper strips and matchbox.
