Cheap and interesting chemistry Practicals

affiliated to "A Ray of Hope UNESCO Youth Ambassador for the Culture of Peace"

This site gives an opportunity for chemistry teachers from around the world to show, and give to others, their experiment ideas on using simple materials instead of costly sophisticated apparatus. If you can send me any ideas with pictures and notes I will be very happy to publish them on this site. Copyright is all yours, there are no hidden deals on this site, its all about sharing good low cost chemistry experiments.
