Zinc strips for science experiments, plz can anyone tell me where to get them.?

I am trying to do a science course and i love to be able to test the theories, i am having trouble finding the things i need. if somebody can tell me any nice science equipment suppliers online i would be grateful.
Answer
Most scientific suppliers offer zinc metal as thin sheet which can easily be cut to shape with ordinary scissors. try phillip harris, timstar, scientific and chemical, or any of the school science suppliers. all have online catalogues.
