Or maybe not. You decide. Specially dedicated to those who want to know how to set up a photographic lab at home, here are some interesting sites:

Jack’s Photographic and Chemistry Site
Chemistry of Photography (Cheresources)
CHEM 2502 Chemistry of Photography Laboratory

Some examples: a plastic hydrogen bomb (!), building a hydrogen fuel cell, simple heat engines, a film can cannon, a metal that melts in hot water, a Bernoulli levitation ball, the impossible kaleidoscope and much more.

Another interesting experiment is DNA Extraction From Wheat Germ. Also recommended: DNA Extraction Biotechniques Virtual Laboratory.

Thoughts Aside: A kitchen island is an absolute necessity of a modern kitchen today, no matter what part of the world it is in. The question of preferred kitchen faucet, cabinet etc comes later.

The site has a very simple layout with links pointing to other sections of the site. The two most interesting of these sections are a Virtual Textbook and a Virtual Laboratory with several experiments descriptions.
