Hundreds of liquids, from fruit juices to specially formulated chemicals, can be used as invisible ink. Here we explore six of the most interesting and accessible types. We hope you’ll be inspired to make your own invisible ink at home. With a bit of practice, you too can become a master of steganography (which is the art of writing hidden messages, in case you didn’t know that already!)
This interpretation of Dante’s Divine Comedy is precisely the experience video artist Marco Brambilla (director of Demolition Man) and Toronto-based studio Crush were striving for in Civilization, a video mural created for the new Standard hotel in New York City.
The entire mural uses over 400 video sources, including samples from several films—something Brambilla is well-known for in his work. This particular project came with some special technical challenges, though.
In 1995, scientists confirmed the existence of the Great Smoky Mountain synchronized fireflies, and have subsequently discovered other populations in the Congaree Swamp in South Carolina and other high altitude locations in the Appalachian mountains. As this curious phenomenon remained undiscovered for years, it is quite possible that there are other varieties of fireflies blinking in unison throughout the United States, perhaps even in your own backyard.
After a few days of returning to the semi-desert national park in far northern New South Wales and talking to and sitting with the kangaroo, the researcher was able to get close enough to her former orphan to open her pouch.
In a matter of seconds, Mr Edwards managed to slip in a macro lens and capture this rare glimpse of life inside the marsupial’s pouch. The photo – of a newborn joey, known as a pinkie, suckling the mother’s teat – is being exhibited as part of the New Scientist Eureka Prize for Science Photography Exhibition in Sydney.
“It was one of those frames you don’t get very often,” Mr Edwards told The Times.
Rouslan Toumaniantz, who runs the tattoo parlour called The Tattoo Box in Courtrai, denies her claim.
He said she knew 'exactly what she wanted'.
He added: 'She was awake and looked into the mirror several times as the procedure was taking place.
'The trouble all started when she went home and her father and boyfriend threw a fit.
'They are saying things now like I doped her or hypnotised her. What rubbish!
'She asked for 56 stars and that’s what she got.'
The one dollar bill is the most ubiquitous piece of paper in America. Collage asks the question: what might be done to make it something else? It is a ripe material: intaglio printed on sturdy linen stock, covered in decorative filigree, and steeped in symbolism and concept. Blade and glue transform it-reproducing the effects of tapestries, paints, engravings, mosaics, and computers-striving for something bizarre, beautiful, or unbelievable... the foreign in the familiar.
When they are old enough - in about two months' time - Mr Lara will release them back into the wild.
The tiny creatures, who are being bottle-fed, are Common Armadillo (Dasypus novemcinctus), an endangered species, and were found and rescued by Mr Lara of environmental organisation Alerta Mundial (World Alert).
Mr Lara eventually wants to create a rescue centre that will focus on restoring the natural habitat of the armadillos and other at-risk creatures.
