A young Australian man had an idea for a business like no other: He’d mail your enemies a “glitter bomb,” an envelope full of annoying glitter that would get everywhere and ruin the recipient’s day. The business was an immediate success, thanks to the coverage in media outlets like Time, Huffington Post and Fast Company. He became so overwhelmed with orders that he couldn’t keep up, and he put his website up for sale for $85,000 after just one day in business. Now he says the whole thing was a hoax he played on the media. Was it really? That and more in our weekly web roundup.
