Eggs are fragile and do not stay fresh for long, but they are also used to make all sorts of yummy stuff. If you’re an egg fan, or even if you aren’t, you will definitely like these simple science fair project ideas involving the ‘yellow eye'.

The Unbreakable Egg
We know eggs are fragile and must be handled with care. Here’s an easy science fair project idea that makes eggs unbreakable.

You will need:
- An egg
- Cling film

Instructions:
- Wrap the egg in cling film.
- Place it in your palm and wrap your fingers around it.
- Make sure you cover the egg entirely and squeeze hard. Apply equal pressure from all sides.
- If you've done it correctly, the egg should remain unbroken.
- Try the same procedure without the cling film. Did it make a difference?

What’s happening?
Egg shells are fragile but the shape of the egg isn’t. If you apply pressure evenly all over the shell, it will remain in one piece.

Bouncing Eggs
Do eggs break when dropped? That’s a no-brainer, right? This tricky science fair project idea will make you think again.

You will need:
- Eggs
- Vinegar
- Hard flat surface

Instructions:
- Place a few eggs in vinegar and let them sit for a few days.
- This will make the shells come off easily and you will be left with the delicate membrane.
- Wash the eggs carefully so they don’t break.
- Now take one of the shelled eggs and drop it from a low height to make it bounce.
- Try dropping it from different heights to see from what height it breaks.
- Try bouncing it on different surfaces to see if it makes a difference.
- Draw a table to demonstrate your findings.

What’s happening?
Egg shells are made of calcium carbonate. When it is exposed to acetic acid (also known as vinegar), it will react by dissolving. But the membrane inside remains unharmed. The egg becomes rubbery and will bounce.

The Floating Egg
Impress your teachers and classmates by making an egg float. This cool science fair project idea will get you started!

You will need:
- An egg
- Table salt
- A large bowl filled with tap water

Instructions:
- Fill the bowl two thirds full with water.
- Place the egg gently into the bowl. It will sink to the bottom.
- Now take the egg out and add 5 tablespoons of salt to the water. Place the egg again in the bowl. If it doesn’t float, try more salt until the egg floats.

What’s happening?
Objects sink in water because they have more density than water. When you add salt to water, you are increasing the density of water. That’s why the egg will float in salty water.
