Salt Crystals Science Experiment
In this fun and easy crystal science experiment, we’re going to grow salt crystals.
Note: Since hot water in involved, please insure adult supervision is utilized.
- Piece of string
- Hot water
- Fill the jar with hot water.
- Slowly stir in several tablespoons of salt.
- Tie one end of the string around the nail.
- Next tie the other end of the string around the pencil in a way that the nail will be suspended just above the bottom of the jar when the pencil is laid across the mouth of the jar.
- The water will dry up after several days and your string will be covered with salt crystals.
How it Works:
The salt dissolves in the heated water. As the water cools, it becomes less able to hold the salt. The salt then clings to the string and forms crystals.
Make This A Science Project:
Experiment with different types of solutions and observe and record any differences in the rate of crystals creation. Some ideas may be Epsom salts, Borax, or sugar (do not eat).
