Egg & Vinegar Science Project

During the summer, we had this egg and vinegar science project where I showed my children how acidic the vinegar is that it able to dissolve the egg shells.

To do this project, you will need:

• Big glass jar with big opening and cap
• Vinegar
• Egg
• Spoon

Method:

1. Fill half of the jar with vinegar.
2. Drop the egg slowly into the jar and top it up.
3. Watch the bubbles around the eggshell. Cover the cap and leave it for 24 hours.
4. Use the spoon carefully to spoon out the egg. If there are still undissolved eggshell, pour out the old vinegar and add new vinegar in it and wait for a few more hours.
5. Do remember to use jar with a big opening/neck as the egg will expand. If the opening is too small, your egg will not slide out.
6. This is how it looked when the vinegar dissolved the eggshell. My daughter is holding a naked egg.
