Post all of your good science fair project ideas here.


Try making copper sulfate.

 

Dissolve epsom salt in water.

connect two 9-volt batteries up in a series circuit.

connect those batteries(using wires) to 2 copper leads that hang down into the epsom salt solution

After a few days (and many batteries) you will have copper sulfate

slowly (very slowly to prevent it from running over you container) pour the copper sulfate through a coffee filter

the filtered version is the finished product

Why don't you use rectifier such as KBPC610 (6 A, 1000 V) which cost $0.5 and optionally fuze (6 A for KBPC610) and capacitor 450 V >100 nF, and regular AC 230 V?

You won't be wasting batteries, and will have result very quickly.

Copper sulfate has many industrial and agricultural uses, but is this project efficient and can it be presented in an innovative manner?
