Step 1: Materials
1) Copper Sulphate in powder form
2) A glass jar
3) A small button
4) Some thin (plastic coated) wire
5) A paper clip
6) A spoon
Step 2: Prepare the "Crystal Seed"
Then, cut the wire in half so that you have two pieces. Tie each wire to each side of the paper clip.
This arrangement ensures that the "seed" remains submerged in the saturated solution.
Step 3: Prepare the Solution
Add copper sulphate to the hot water and dissolve. Keep on adding copper sulphate until no more dissolves. Repeat this process until the jar is almost filled to the top with solution. Remember: it is extremely important that the solution is saturated! This means that if you add any more powder to it, it does not dissolve after stirring well. Your solution should be dark blue, and no light should pass through it. Copper Sulphate is very soluble and can be absorbed through the skin, so please wear gloves when preparing the solution.
Step 4: Place the "Seed" and Wait
