两个演示显示了五层或六层液体的不混溶性。两个演示的设置都是这样的：多相混合物中的一个均匀层在摇动时分离成两个新层。五层演示所用溶剂为甲醇、甲苯、石油醚或正戊烷、硅油、全氟庚烷和水。添加汞产生第六相。
Two demonstrations are presented that show the immiscibility of five or six layers of liquids. The setup of both demonstrations is such that one homogeneous layer in a multiphasic mixture separates into two new layers upon shaking. The solvents used are methanol, toluene, petroleum ether or n-pentane, silicone oil, perfluoroheptanes, and water for the five-layer demonstration. Addition of mercury results in a sixth phase.
