O acendedor de um isqueiro é um exemplo fascinante de engenharia compacta. Ele contém componentes minuciosos, como o cristal piezoelétrico e o espaço de faísca, que, ao serem ativados, geram uma faísca capaz de acender o combustível. Embora seja um objeto simples, esse mecanismo miniaturizado combina precisão e funcionalidade, sendo uma verdadeira obra-prima da engenharia. Frequentemente negligenciado, o isqueiro é um ótimo exemplo de como a inovação pode ser encontrada nos itens mais cotidianos
