This simple experiment is a fun learning activity. Combining vinegar and bicarb makes all sorts of oozing, bubbling reactions.
What you'll need:
- Raw Egg
- Glass or Jar
Lets get started:
- Get a raw egg and carefully place it into a glass or jar.
- Fill the glass with white vinegar until the egg is completely submerged.
- Leave the egg in the glass for 48-72hours.
- When the egg has started to become translucent you will know it is ready.
- Remove the egg from the glass and gently rinse it under some tap water. It will feel rubbery.
- Lift the egg 1-2 inches in the air, let go, and watch it bounce. Just be sure not to bounce it too high unless you are ready for a messy result!
How it Works:
The shell of an egg is made of calcium carbonate. When you place the egg into the vinegar, you see bubbles, which is the chemical reaction of the acid in the vinegar reacting with the calcium carbonate to produce carbon dioxide. You’ll also notice that the egg gets larger as it sits in the vinegar. That is because some of the vinegar is absorbed in the egg through its semi-permeable membrane!
