Easy Egg Experiments For Easter Science – Part 1

There are lots of easy and fun science experiments that you can do involving eggs. Even younger kids will get a kick out of some of them, although they won’t understand the “science” behind the trick. Here’s a few I’ve come up with.

Most children decorate eggs for Easter, but here’s a way to get in a little science experiment with your decorating.  Is it possible to actually etch an egg without breaking it?

What You’ll Need:

• Hard Boiled Egg
• Crayons
• Widemouth Jar
• White Vinegar

What to Do:

1. Draw on your egg with the crayons. You create designs, write words, or even just scribble. The color of the crayons doesn’t matter. Be very careful not to crack the egg when you are writing on it.

2. Put the egg into the widemouth jar and cover it with white vinegar.

3. Let the egg stand in the vinegar for two hours and then pour out the vinegar and replace it with fresh vinegar.

4. Let the egg stand in the fresh vinegar for another two hours, then take it out of the jar. Wash the egg and remove all the crayon marks. This will create an etched egg shell.

Why This Works

The crayon acts as a protective barrier to the vinegar. The acid in the vinegar dissolves much of the calcium carbonate of the eggshell. The wax in the crayons protects the parts of the shell that you wrote on and keeps it from dissolving.

Kids never cease to be amazed by this little trick, no matter how many times you show it to them.

What You’ll Need:

• 1 Hard Boiled Egg Peeled
• Boiling Water
• A Bottle with a neck slightly smaller than the egg

The Experiment:

1. Set the egg on the neck of the bottle to demonstrate that the egg simply won’t fit in the bottle. Tell the child that you know a trick to make that egg go down into the bottle without breaking it.

2. Remove the egg from the bottle and pour the boiling water into the bottle. Carefully roll the water around in the bottle and then pour it out.

3. Quickly put the egg back on the neck of the bottle, while the bottle is still hot, and wait for it to get sucked down into the bottle.

The Explanation:

When you put the hot water into the bottle and then poured it out, the hot water left steam behind in the bottle. The steam forces out some of the air that was already in the bottle. As the steam in the bottle cools down, it converts into tiny droplets of water. The drops of water require less space and this reduces the amount of air pressure in the bottle. The pressure on the outside of the bottle is greater than the pressure on the inside of the bottle and that is what forces the egg into the bottle.

Removing The Egg From The Bottle

You can remove the egg from the bottle using the same process in reverse. Hold the bottle upside down and blow into the bottle for about 30 seconds. Be sure to seal your lips around the mouth of the bottle when you do this. By blowing into the bottle, you will increase the pressure on the inside of the bottle and force the egg out.
