What was meant to be a festival of light turned into a nightmare for many families in Madhya Pradesh, India. During Diwali celebrations, 14 children lost their eyesight permanently, and over 120 others suffered severe eye injuries after using homemade “carbide guns” — toy-like firecracker devices sold openly in local markets for just ₹150–₹200. These improvised explosive toys, made from plastic or tin pipes filled with gunpowder, match heads, and calcium carbide, cause violent explosions when ignited. The blasts released hot metal particles and toxic fumes that burned retinas and damaged irises beyond repair. Hospitals in Bhopal, Indore, Jabalpur, and Gwalior are overwhelmed with injured children. Authorities have arrested six people linked to illegal sales, while doctors warn that these are not toys but deadly explosives. Experts blame viral “firecracker gun challenges” on social media platforms like Instagram and YouTube for fueling the dangerous craze.
