 Marbled Eggs

 

Paragraph about experiment

What's going on? 

Nail varnish is lighter than water, so it sits on the water’s surface. When you lay the egg over the pattern, it sticks to the egg instead to create a pattern.

 

 

 

 

 Floating Eggs

 

 

Paragraph about experiment

What's going on? 

 Unlike the fresh water we drink, oceans are made of salt and water. Eggs sink in fresh water because they are more dense than fresh water. This means that an egg-sized amount of fresh water weighs less than an egg. But adding salt makes the water in the glass denser than the egg, this is why eggs float in salty water!

 

 

 

 

 

 Naked Eggs 

 

Paragraph about experiment

What's going on? 

A naked egg is an egg with no shell. The acidity in the vinegar reacts with the egg and dissolves its shell. The only thing that remains is the delicate membrane of the egg surrounding the yolk and egg white.
