Read the seeds: Braille on hamburger buns JOHANNESBURG, South Africa, Jan. 17 (UPI) -- A restaurant chain in South Africa is offering blind customers a chance to read the seeds on their hamburger buns, a YouTube video announces. The video shows sesame seeds being placed on a hamburger bun before it is baked. The sesame seeds unusual gesture? They spell out words in Braille. The gesture is a publicity stunt meant to promote the new Baille menus at Wimpy restaurants, The Los Angeles Times reported Monday. It is unclear how long the restaurant chain will continue producing hamburger buns with braille words spelled out in sesame seeds, but the ad says the 15 people who enjoyed the hamburgers passed the word on to 800,000 others through other Braille organizations, the newspaper said.
