Quando um tapete é dobrado, o ar preso nas dobras é comprimido, criando uma área de alta pressão. Segundo a Lei de Boyle, a pressão de um gás aumenta quando seu volume diminui. Ao tentar prender o ar dentro do tapete dobrado, o homem está forçando esse ar comprimido em um espaço menor, elevando ainda mais a pressão. Ao soltar o tapete lentamente, o ar escapa rapidamente, ajudando a desenrolá-lo com menos esforço. Essa demonstração ilustra como o controle da pressão do ar pode tornar tarefas mais
