Drilled Balls Set – Mixed Materials (25mm, Pack of 12)

The Drilled Balls Set of 12 is a versatile and practical resource designed for a wide range of school science experiments. Commonly used for pendulum investigations, this mixed‑material set allows students to explore how mass, material, and density affect motion, while also supporting many other laboratory activities.

Each ball measures 25mm in diameter and is precisely drilled with a 3mm diameter hole, making them easy to suspend using string, thread, or wire. The set includes two balls each made from wood, aluminium, steel, cork, brass, and lead, providing clear contrasts in mass and density. Supplied in a handy plastic storage box, the set is easy to organise, store, and transport between classrooms.
