For this experiment, the apparatus and materials they needed were,
- A clean wide-mouthed beaker.
- Boiled water.
- Non- iodized table salt. (Up to ½ cup)
- Food colouring of desired choice.
- A pencil.
- Sturdy string.
- One tablespoon and teaspoon each.
- Stirrer.
- Bunsen burner.
- Wire gauze along with a tripod stand.
- Fill about half of a beaker with boiled water.
- Add some food colouring to get the desired colour.
- Add several tablespoons of salt into the beaker and stir using a stirrer until the salt dissolves. Then, continue adding salt, about a teaspoon at a time, until the salts start collecting rather than dissolving.
- Tie a string around the center of a pencil. Balance the pencil on the top of the beaker with the string hanging inside the beaker. Adjust the string so that it ends just above the water.
- Place the beaker in a spot in the lab where it will not be disturbed.
- Check the beaker daily for about a week or so. Record the progress of the crystal formation and observe the change in height of the water level.
