A closer look

Before this violent accident, rubber shoes would literally melt into a sticky soup during summer and freeze into brittle shards during winter. Charles Goodyear spent years aggressively failing to fix raw rubber until he clumsily dropped a mixture of rubber and sulfur directly onto a blistering hot stove. Instead of melting, the material instantly charred into a durable, weather-resistant polymer, completely revolutionizing global transportation via tires.
