How to Make Salt Crystals
Boredom blues? Science crave? This fun and interesting project will cure both!
[edit] Steps
- Fill a glass jar about halfway with tap water.
- Add some food colouring for a pretty color. Add as much as necessary to the water get the desired color.
- Add about 2-3 tablespoons of salt to the mixture and stir with a spoon until you can't see the salt grains, then put more salt in it and shake it!!!
- Tie a string around a pencil or small stick.
- Cut the string so that it hangs just above the water.
- Balance the pencil/stick on top of the glass jar with the string hanging inside the glass jar just above the water.
- Leave it on a table for 1-3 weeks and check every day to see if there are salt crystals on the string.
[edit] Tips
- Use sturdy string, but thin string.
- Use stand-out shades of food colouring, like bright ruby red or sapphire blue, for an interesting effect.
- Heating the water up before adding the salt will help the salt dissolve (ask an adult for this part)
- Alternatively, you could put the string in the water and see what happens.
