5-Metal Hooked Density Cylinders Set (Copper, Tin, Aluminum, Zinc, Stainless Steel)

This 5-piece hooked metal cylinder set features cylinders made from copper, tin, aluminum, zinc, and stainless steel. Each cylinder has the same 0.5-inch (12.5mm) diameter and 30g mass but varies in length according to the metal's density. The hooks allow easy lifting from boiling water and easy attachment to spring scales (not included). The set includes a complete instruction manual with background information and inquiry-based student activities. Tolerances are approximately ±5% as the cylinders are designed for educational use rather than ultra-precision machining. Some surface oxidation may occur and can be scuffed off. Part of the Eisco Labs Density Investigation series.
