Does anyone remember how to make a regular egg bounce like a bouncy ball?? i need step by step directions...?

Answer 1

Make an egg bounce



For this Year 6 science experiment you need:

2 eggs

water

vinegar

a torch

2 drinking glasses

a bowl

What to do:

Put 1 whole raw egg in a glass of water.

Put 1 whole raw egg in a glass of vinegar.

Leave them for a few hours.

Have a look at the eggs. The one in the water is the same. The one in the vinegar has started to fizz. The acid in the vinegar is dissolving the calcium carbonate that is in the shell.

Touch the egg in the vinegar. It should feel like a rubber ball.

Leave both eggs alone for 7 days.

Take the vinegar egg into a dark room and shine the torch at it. The light should bounce off the egg. When this occurs:

Take the vinegar egg out of the glass. Hold the egg over the bowl.

Drop the egg

What happens:

The egg bounces.

Try it again getting a little bit higher each time. See how high you can make the egg bounce. Now try it with the egg from the glass of water.

Why it happens: A chemical change occurs in the egg left in vinegar. The vinegar, which is an acid, reacts with the calcium carbonate in the eggshell. The change makes the shell soften, then disappear. This is known as "decalcifying". The egg in the glass of water does not change (unless it's hot water, in which case the egg will cook...but that's another story).

Answer 2

try seaching yourself: http://www.google.com/search?q=make+an+e...

Got a 1000 hits. Learning to use seach engines is basic to internet use.

Too lazy Asslee?

Answer 3

just trow it..

they bounce all the time

Answer 4

VINEGAR

Answer 5

sure:

1: you need a little tupaware bowl.

2: fill the tuparware bowl with vinagar and put in a hard boiled egg.

3: Then just leave it there for some time and then bounce it.

Answer 6

My granddaughter had to do this experiment too.

We used the recipe below in the link to do this.  There are other helpful experiments too on this link.

Have fun with your rubber egg ball!!!
