Os famosos CDs (Compact Discs) parecem simples, mas têm várias curiosidades interessantes: 🔹 Arco-íris natural: aquele efeito colorido que aparece quando você gira um CD acontece por causa das micro-ranhuras na superfície, que refletem a luz como um prisma. 🔹 Capacidade curiosa: um CD comum armazena cerca de 700 MB ou até 80 minutos de áudio. Existe uma história de que esse tempo foi escolhido para caber a 9ª Sinfonia de Beethoven inteira sem cortes.
