For this experiment you will need a fresh, uncooked egg, a drinking glass, a dissolving solution such as white vinegar or a cola beverage, and 4-5 days of patience. The drinking glass needs to be large enough for the egg to touch the bottom without touching the sides of the glass.

After the Coca Cola and egg was left for a year, the soda reacted with the egg shell made up of calcium carbonate reacted with the acid and the result was surprising. All that was left in the bowl was some brown disgustingly gooey mess.

If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. Soak one egg in vinegar for 24 hours (1 day), one egg for 48 hours (2 days) and one egg for 72 hours (3 days).

The little bubbles you see in the water are made of carbon dioxide gas; just like the bubbles from your vinegar and baking soda volcano. Once the shell is gone, the vinegar will cross over the semi-permeable membrane (through a process called “osmosis”) and slightly inflate the egg.

When you put a naked egg in corn syrup, you are creating a situation where the egg membrane separates two solutions with different concentrations of water. The egg white is about 90% water; corn syrup is about 25% water. So water migrates from inside the egg to outside the egg, leaving the egg limp and flabby.

Leave the egg in the water for 24 hours. Osmosis will occur; that is, the water will migrate from the side of the membrane where water molecules are abundant (i.e. outside the egg) to the side where water molecules are less abundant (inside the egg). After 24 hours, the egg will be plump again!

To perform the float test, gently set your egg into a bowl or bucket of water. If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air.

Orange juice and vinegar both contain acids which react with the calcium carbonate in the eggs to produce carbon dioxide gas. This is why the eggs fizz in those liquids. Over time, this reaction has the effect of destroying the egg shells and leaving behind the inside of the egg.

While it’s generally safe to consume raw eggs, there are very few reasons to do so. Raw eggs typically contain the same benefits as cooked eggs but they don’t aid nutrient absorption quite as well.

Eggs are a low-calorie food rich in protein and other nutrients. Eating eggs may support weight loss, especially if a person incorporates them into a calorie-controlled diet. Research suggests that eggs boost metabolic activity and increase feelings of fullness.

Raw eggs are a nutrient-dense food packed with protein, good fats, vitamins, minerals and antioxidants that protect your eyes. They’re also an excellent source of choline. The yolks contain most of the nutrients.

The science is clear that up to 3 whole eggs per day are perfectly safe for healthy people. Summary Eggs consistently raise HDL (the “good”) cholesterol. For 70% of people, there is no increase in total or LDL cholesterol. Some people may experience a mild increase in a benign subtype of LDL.

Eating raw eggs for protein? Your body absorbs more protein and biotin when you eat cooked eggs. In the bodybuilding world, adding raw eggs to shakes and smoothies is considered a quick way to get more protein to build muscle.

There is no recommended limit on how many eggs people should eat. Eggs can be enjoyed as part of a healthy, balanced diet, but it’s best to cook them without adding salt or fat.

Eggs: the perfect post-workout snack Eggs provide all of the nine essential amino acids (also known as the building blocks of protein), making them an effective food for maintaining, building and repairing muscle. For a portable snack to enjoy post-workout, you can’t go wrong with a simple serving of hard boiled eggs.
