How do you translate Coca-Cola into Singaporean English? Hug Me is the premise of a new marketing campaign that Coke launched, reports Forbes. A Coke vending machine was installed at the National University of Singapore, but instead of the Coke logo, this machine says Hug Me in the logo font. And instead of money, it responds only to the currency of hugs. You have to squeeze the sides of the soda dispenser in a specific way to make a free Coke come out. In a statement as part of the company's 'Open Happiness' campaign, Leonardo O'Grady, ASEAN IMC Director, The Coca Cola Co., explained that: "Happiness is contagious. The Coca Cola Hug Machine is a simple idea to spread some happiness. Our strategy is to deliver doses of happiness in an unexpected, innovative way to engage not only the people present, but the audience at large." ... Three-quarters of Australian children in their final year of primary school believe cotton socks come from animals and 27 per cent are convinced yogurt grows on trees, reports the Sydney Morning Herald. A national survey of year 6 and 10 students by the Australian Council for Educational Research found huge gaps in young people's knowledge of basic food origins. In a hypothetical lunch box of bread, cheese and a banana, only 45 per cent of six-yer-year olds could identify all three as from farms. The survey also found most children believed timber was mostly harvested from native forests and about a third thought wildlife could not survive on farmed land ...

Tobacco has moved behind the bar and is becoming a hot item in cocktails, reports The Guardian. Tobacco-inspired mixed drinks have been around since at least 2003 when various cocktail makers tried to recreate the effects of smoking in a drink. For instance, a group of Florida cocktail makers infused vodka with tobacco leaves in a Nicotini, while in New York, Smokeless Manhattan combined Laphroaig whisky, orange bitters and port. Now, cocktail makers are using distilled tobacco in their drinks, such as Perique Tobacco Liqueur, made in France with distilled Louisiana Perique by Ted Breaux. "It's made in roughly the same way as gin is," said Breaux. "But instead of using juniper berries we use tobacco. The concept was to take an immensely powerful substance and then to reduce it through distillation into something very subtle but full of flavor. Breaux said sales are soaring. "We're struggling to keep up with demand," he said. "A lot more people are starting to order it across Britain and Japan. And our plan is to start selling it to the USA next year." Breaux said downing the liqueur is completely different from smoking. "The end product comes in a form that greatly diminishes the health concerns associated with tobacco use," he said. "After distillation you end up with none of the nasties like cyanide, tarry compounds or carcinogens that you'd get from a cigarette. And only a trace amount of nicotine." ... Scientists in the U.K. are now accepting orders for their Choc Creator, an invention that lets users "print their own custom-made sweets, layer by layer," reports Gadgets and Gizmos. According to the BBC, "You just need to melt some chocolate, fill a syringe that is stored in the printer, and get creative printing your chocolate," said project leader Dr. Lian Hao of the University of Exeter.
