My science experiment - Egg Drop or Balloon Drop

Objective:

•The object of the challenge was to somehow get the whole egg into the bottle without harming the egg. (You can substitute the egg with a balloon.)

Play Video to see the experiment

Procedure: First get a bottle, an egg, a lighter, and a piece of paper.
Use the lighter to light the paper on fire.
Put it in the bottle and place the egg in immediately after.
The egg will slide inside with a popping sound.
Now blow all the smoke out.
Put your mouth on the bottle and blow while the bottle is upside down.
Then keep it upside down and the egg will fall out in a few seconds.

Tricks:
Put vegetable oil on the rim of the bottle so the egg will slip a little more easily.
If you wet the egg the egg will also slip a little more easily
Make sure the opening of the bottle is smaller than the egg but reasonable big.
Make sure you put the lit paper inside the bottle and the egg on top of the opening very quickly

How it works
The burning piece of paper heats the molecules of air in the bottle and cause the molecules to move far away from each other.
When the flame goes out, the molecules of air in the bottle cool down and move closer together.
This is referred as a "partial vacuum ".
Now the air outside the bottle would come rushing in to fill the bottle. However, the egg is in the way!
The "push" or pressure of the air molecules outside the bottle is so great that it literally pushes the balloon into the bottle.



Application
Weather Patterns - This tells me how the low pressure and high pressure areas impact weather. "nature abhors a vacuum."

We went to this restaurant on the way back from the mandir.
I liked their garlic naan and cholay.
The dahi batata sev puri was also very good - almost as good as chaat paradise.

My dad really enjoyed the Ooondhio (a vegetable dish). He said it was the best ever he has ever had. He said the srikhand (comes with the Ooondhio) tasted like home made, was very very good too.

This restaurant is definitely worth checking out.
