Crystal Growing

There are many different techniques for having fun with crystals. One of the most colorful methods involves dropping metal salts like calcium chloride, lead nitrate or copper sulfate into a solution of sodium silicate, but you will need to borrow those from the school's chemistry lab.If you would rather use off-the shelf materials for your crystal growing experiments, you can create a warm saturated solution with a crystal solute like salt, sugar, alum or aniline. Dip a bit of string into it and wait for it to cool off. The particles in the solution will aggregate around the surface of the string and create tiny seed crystals.After a few days you will have some gorgeous crystal formations.
