- Which takes up more space, water or ice?
“Most substances take up less space when frozen than when liquid. Ice from water on the other hand occupies more space than the original liquid water did.”

Tip for saving energy in the home
Replacing an electric water heater with a solar model can reduce water heat costs by 50 to 80 percent every year - and over the 20-year life of the equipment, more than 50 tons of carbon dioxide emissions will be displaced.
Ancient crystal skulls
It is claimed that 13 ancient crystal skulls have been found with mysterious properties.
The Mitchell-Hedges family loaned the skull to Hewlett-Packard Laboratories for extensive study in 1970. Art restorer Frank Dorland oversaw the testing at the Santa Clara, California, computer equipment manufacturer, a leading facility for crystal research. The HP examinations yielded some startling results.
Researchers found that the skull had been carved against the natural axis of the crystal. Modern crystal sculptors always take into account the axis, or orientation of the crystal's molecular symmetry, because if they carve "against the grain," the piece is bound to shatter -- even with the use of lasers and other high-tech cutting methods.
To compound the strangeness, HP could find no microscopic scratches on the crystal which would indicate it had been carved with metal instruments. Dorland's best hypothesis for the skull's construction is that it was roughly hewn out with diamonds, and then the detail work was meticulously done with a gentle solution of silicon sand and water. The exhausting job -- assuming it could possibly be done in this way -- would have required man-hours adding up to 300 years to complete.
