What you'll need:
- A jar
- About half a cup of salt
- A spoon for stirring
- 2 toothpicks
- Fill the jar with water.
- Add about half a cup of salt to the water.
- Mix the solution together with a spoon.
- Cut a piece of string with scissors and tie each end to a toothpick.
- Place the string over the top of the jar so that the string dangles into the middle of the solution and the toothpicks hang over the edge.
- Don’t forget to clean up when you’ve finished.
