A closer look
In Victorian London, the fear wasn’t darkness — it was explosion. Street lamps ran on gas piped underfoot, often leaking. A child’s dropped match could blow half a block. To fix it, inventors created ‘safety flames’ — tiny mesh cages that allowed light but blocked fire from igniting gas outside. That same safety principle now lives inside spacecraft, mining helmets, and camping stoves. History hides invisible inheritances: every small Victorian streetlamp quietly parented modern fire safety regulations. So when you see a glowing lantern in an old photo, you’re also looking at the ancestor of modern biospheres and high-pressure containment labs.
