 Project description:
If you ever thought that chemistry is complex and hard to learn, you need to do this project. In this project you will make three different products. Each of them can be a successful money making business. All materials that you need can be found at home or obtained locally.
 Details of this project:
More details or support for this project is available for the members of web site. Laboratory supplies needed for experiments of this project may be purchased from; however you are also able to substitute such equipment with household items.
