O experimento da lâmpada de lava demonstra os conceitos químicos de densidade, polaridade, solubilidade e reações químicas. A água e o óleo não se misturam por terem densidades diferentes e polaridades distintas . A pastilha efervescente reage com a água, liberando dióxido de carbono , um gás que carrega bolhas de água colorida para o topo, criando o efeito de "lava".
