Turn out the lights and allow your eyes to become accustomed to the dark. Then, while looking into a mirror, pop a wintergreen Life Saver into your mouth and chew. Charge separation is produced as the candy fragments, and the discharge produces light. This phenomenon is called triboluminescence and can be observed with other flavors of hard candy--or even sugar cubes, but wintergreen flavor seems to work best.

Pykrete

Pykrete (also known as picolite) is a composite material made of approximately 14% sawdust (or, less frequently, wood pulp) and 86% water by weight then frozen, invented by Max Perutz and proposed during World War II by Geoffrey Pyke to the Royal Navy of the United Kingdom as a candidate material...

Brillouin Zones

Brillouin Zones are particularly useful in understanding the electronic and thermal properties of crystalline solids.

Useful chemistry

Useful chemistry is an open source science project which commenced in 2005 with the aim of making "the scientific process as transparent as possible by publishing all research work in real time to a collection of public blogs, wikis and other web pages". The project resources include UsefulChem-molecules, where users can post details of molecules relevant to the project; the UsefulChem wiki of laboratory experiments; and the UsefulChem blog which focuses on project milestones. Contributors can post chemistry problems and assist in solving problems posted by others. UsefulChem is led by the Bradley Laboratory at Drexel University.

Non– Newtonian Fluid experiment

Have you ever turned a liquid into a solid just by tapping on it? In this experiment from University of Wisconsin-Madison Chemistry Professor Bassam Z. Shakhashiri, you make just such a liquid.

Gluep: Solid or liquid?

Plastics are all around us. There are many different kinds, with a wide range of properties. Some are hard, others are soft. Some are transparent, others are opaque. In another experiment from University of Wisconsin-Madison Chemistry Professor Bassam Z. Shakhashiri, you can make Gluep yourself.

Chem Spider for structure searches

This allows searching of structures, sub-structures and formulae with various criteria

Gas (Methane) Hydrates -- A New Frontier

Methane trapped in marine sediments as a hydrate represents such an immense carbon reservoir that it must be considered a dominant factor in estimating unconventional energy resources; the role of methane as a 'greenhouse' gas also must be carefully assessed.
