i need some ideas to make the 12th class (investigatory) chemistry project.

 

it should be something that requires minimum of 1hr. of lab work & should contain chemicals which are usually available in the school chemistry lab.

also, it should not be dangerous....

 

plz i really need those ideas....

 

 

P.S. the lab manual projects hav already been taken, so plz suggest something different...

 i put this topic for experts so that the 12th class & passout experts can also help...

 

thanks in advance...
