Khaberni - Surveillance cameras in a mobile phone store in India captured an unusual incident, where a teenager bit into a "lithium-ion" type smartphone battery, causing it to explode instantly and turn into a ball of flames inside his mouth; this resulted in him sustaining severe burns to his face.
The incident began when the boy stood in front of the maintenance platform and, unexpectedly, put the battery between his jaws, and due to the mechanical pressure on the chemical cell, his teeth pierced the outer casing, causing a massive thermal jump.
