Gum Explosion: Vladimir Likhonos

Vladimir Likhonos, a 25-year-old Ukrainian student, died in 2009 when his chewing gum exploded. He had a habit of dipping gum in citric acid for a sour taste, but police found 100g of unidentified explosive powder on his work table. He may have accidentally coated his gum with the explosive powder, mistaking it for citric acid. The explosive was four times stronger than TNT and may have been triggered by his saliva or chewing pressure.
