摘　　要：熔岩灯实验是最具观赏性的化学科普实验之一,通常用泡腾片作为熔岩灯的引发剂。在泡腾熔岩灯的启发下,设计了两种新型的熔岩灯:苏打熔岩灯和可乐熔岩灯。苏打熔岩灯是以醋和小苏打作为熔岩灯的引发剂,可乐熔岩灯是以可乐或雪碧及曼妥思或盐作引发剂。苏打熔岩灯的原理是酸碱中和的化学反应;而可乐熔岩灯的原理则是物理变化。新设计的熔岩灯原料成本低、反应时间长、更适合对外科普展示和家庭演示。The lava lamp experiment is one of the most amazing popular science experiments of chemistry, and an effervescent tablet is usually used as its initiator. Inspired by the effervescent lava lamp, two new types of lava lamps were designed: soda lava lamp and cola lava lamp. The soda lava lamp was based on vinegar and baking soda as the initiator. The initiators of the cola lava lamp were cola or sprite and mentos or salt. The principle of the soda lava lamp is chemical reaction of acid-base neutralization. The principle of the cola lava lamp is physical change. The newly designed lava lamps have lower raw material costs and longer reaction times, and they are more suitable for the external science exhibition and the family demonstration.
