SBT Instruments Metal Slinky Spring/ STEM Physics Demonstration Coil for Classroom Educational Labs and Fun Activities

• Material : Steel
• Diameter : 7.5 cm
• Stretch up to : 4 meter

The SBT Instruments Metal Slinky Spring is a durable helical coil designed from high-quality steel, made for educational demonstrations and STEM physics experiments. It functions both as a classic toy and a serious scientific tool, ensuring visualization of wave motion (both longitudinal and transverse), oscillations, energy transfer and spring dynamics. Ideal for classroom demonstrations, physics labs, and science fairs, this spring supports hands-on learning of fundamental mechanics and wave phenomena.

Features

• Steel Construction : High-strength steel gives the spring good elasticity, durability and longevity under repeated stretching.

• Large Coil Diameter : Designed to allow easy stretching (e.g., coil diameter of ~ 7.5 cm; length when extended up to ~ 4 meters — typical of many physics slinkies).
• Low Friction : Smooth coils reduce energy loss, making wave motion clearer and more repeatable.

Applications

• Energy Transfer Studies : Visualize conversion between potential energy (when stretched) and kinetic energy (when released).

• Wave Propagation Speed : Measure how fast a compression or tension wave travels across the slinky.

• Gravity & Free-Fall Experiments : Drop the slinky from top, observe how the bottom “hangs” until tension wave arrives — demonstrating propagation delay under gravity.

• STEM Outreach / Engagement : Use in science demonstrations, fairs, or interactive exhibits for students to physically interact with wave mechanics.
