Testing for fresh egg• Put an egg in a

bowl of water, fresh egg will sink to the bottom and lie flat on its side.

• This is because the air cell within the egg is very small. Thus the egg should feel quite heavy.

How to tell hard-boiled egg from raw egg?

• Spin a hard-boiled egg and a raw egg carefully on a countertop. The hard-boiled egg will spins but the raw one will not spin. This is because the hard-boiled egg is solid so everything spins in one direction, while the inside of the raw egg sloshes in different directions and, therefore, doesn't allow it to spin.

Good for your brain

• Eggs give us brainpower. Choline, a substance found in egg yolks, stimulates brain development and function.

• Choline has been recognized as an essential nutrient by Health Canada. Since it is necessary for good health, but is not produced by our body in adequate amounts, a continuous new supply must be provided by our diet. Two large eggs provide an adult with the recommended daily intake of choline.
