Mind sparked on Instagram: "This video highlights an astonishing scientific principle: the hidden power of sunlight when it is concentrated into a single point. Although sunlight feels gentle and spread out, it carries immense energy that becomes intense when focused using a magnifying glass or parabolic mirror ☀️🔍. By bending parallel rays toward one focal point, the lens dramatically increases energy density. At this tiny spot, temperatures rise high enough to melt or fracture solid materials
