“Uma simples bala de ursinho pode literalmente virar carvão usando apenas luz do Sol.” E isso acontece porque essa lente convergente gigantesca concentra a energia solar — cerca de 1.000 watts por metro quadrado em um dia ensolarado — em uma área minúscula. O resultado é um aumento extremo de temperatura no ponto focal. A balinha contém principalmente sacarose, glicose, gelatina e corantes. Quando ela é colocada exatamente no foco da lente, a temperatura sobe tão rápido que primeiro ocorre fusã
