Naked (Rubber) Egg
Professor O will help you learn: Vinegar (an acid) dissolves the hard shell, leaving the bendy membrane - and the egg swells as water moves in (osmosis).
⚠️ The egg is raw inside, so handle it gently over a tray and wash hands afterwards. Don't eat the egg, and don't bounce it hard as it can burst and make a mess.
Steps
- Gently lower the raw egg into the glass so it doesn't crack.
- Pour in white vinegar until the egg is completely covered.
