Hi David,

There are many books written about crystal growing using common chemicals. You should be able to find some at your school or public library. Toy and hobby stores should also have books with this type of information and kits with safe chemicals as well as containers and information about crystal growing.

What you will find in all books will tell you that "crystal growing is an art...." You can try many experiments growing crystals with common chemicals such as table salt, sugar, alum, and epsom salt. You can also ask your science teacher about other chemicals, some very colorful, that can be used to grow crystals.

The purpose of the string is only to provide a surface where the crystals can begin to grow. Other methods commonly used are to use a small piece of rock or a piece of another crystal as a surface where crystal growth can begin.

Good luck.
