Ionic hairbrush

18 December 1999

Here’s one from the bizarre inventions department: an electric hairbrush.
Powered by four AA batteries, an electric discharge from the hairbrush
“stimulates hair follicles and increases blood circulation”, according to its
Japanese manufacturer Tokuyasu, based in Nagoya. The Ionic Hairbrush is said to
achieve its effect by generating ozone and negative ions, which also help to
deodorise hair.

Archaeopteryx. Artwork of the prehistoric feathered reptile Archaeopteryx which lived around 150 million years ago. Discovered in 1861 in southern Germany, it was the first feathered fossil specimen ever found. Despite possessing bird-like feathers, wings and a wishbone, Archaeopteryx also had sharp teeth, finger digits and a bony tail similar to non-bird predatory dinosaurs. This species and numerous other feathered fossils support the theory that modern day birds evolved from prehistoric theropod dinosaurs.
