The Disappearing Eggshell: A Science Experiment for Kids

The Disappearing Eggshell Challenge

• 💡 This "WeWow" tinkering challenge demonstrates the science of awe by making an eggshell disappear.
• 🧪 The experiment involves dissolving the shell of a raw egg while keeping the egg intact, leaving it with a rubbery texture.

Materials Needed

• 🥚 For the disappearing eggshell experiment, you will need a raw egg, a glass jar with a lid, and white vinegar.

Step-by-Step Instructions

• 💧 Step 1: Gently place the raw egg into the glass jar.
• 🍶 Step 2: Fill the jar with white vinegar, leaving about an inch of space at the top to allow gases to escape.
• ⏳ Step 3: Loosely close the lid and leave the jar undisturbed for two to three days.
• 🧼 Step 4: After two to three days, carefully remove the egg from the vinegar and gently rinse it.
• ✨ Step 5: Observe the disappearance of the eggshell, leaving a rubbery, shell-less egg that can be gently bounced.
