Super Star Scientist...

Natalie!

Experiment: Egg Trick

Objective:  When hot air cools, it will create a vacuum

Materials:  egg, bottle, hot water

Natalie, our scientist, had her materials ready and her safety goggles and lab coat on!

First, Natalie read the list of materials and experiment steps from her lab report.

Next, her assistant, Dad, helped pour hot water into the bottle.

After that, they poured the hot water out of the bottle.

Then they placed a hard boiled egg onto the opening of the bottle.

We waited and watched...

...as the egg was s-l-o-w-l-y squeezed...

...down into the bottle...

...a little further...until...

...it went all the way down inside!!

Conclusion:  A vacuum happens because the cooling air needs less space in the bottle.

What a fun experiment, Natalie!
