Smashing Seashells Kitchen Science Experiment
In this fun and easy kitchen science experiment for kids, we’re going to see if we can create a chemical reaction that makes it easy to smash seashells.
Materials:
- Four seashells
- Two glasses
- Water
- Vinegar
- Large spoon
- Paper plate
Instructions:
- Fill one glass with water and one glass with vinegar.
- Place two sea shells in the glass filled with water and two sea shells in the glass with vinegar.
- Wait five days.
- Remove the sea shells and place them on a paper plate.
- Take the spoon and hit the sea shell from the water and see if it breaks.
- Now take the spoon and hit the sea shells from the vinegar. The sea shells from the vinegar should smash easily.

How it Works:
Vinegar is an acid and the calcium carbonate in the seashells is a base. When you add the seashells to vinegar, bubbles start to form on the seashells. This a result of the chemical reaction between the calcium carbonate and vinegar. This chemical reaction produces a gas called carbon dioxide and this is what causes the little bubbles on the seashells. Eventually the vinegar will weaken the seashells a make them easy to smash with the spoon.
Make This A Science Project:
Try different liquids like lemon juice. Try putting eggs or eggshells in vinegar. Try keeping the experiment stored in the refrigerator.
