Steel Springs from the Golden Age of Physics Education

Dear readers,

While exploring the storage room of my school Physics laboratory, I came across another fascinating surviving artifact from a very different era of science teaching: original Griffin & George steel springs, still preserved in their original packaging.

One packet is labelled "Steel Springs - 1 Pair", while another contains 25 steel springs. Judging by the packaging, these were never meant to become museum pieces. They were classroom consumables, designed to be stretched, loaded, measured and experimented with.

Yet decades later, here they are.

Still carrying the famous Griffin lion logo.

Still proudly marked Made in Britain.

And still waiting for the next Physics lesson.

What Were They Used For?

To modern students, a spring may seem like an ordinary piece of metal.

To generations of Physics learners, however, it was one of the most important tools for understanding force, motion and waves.

These springs were commonly used in experiments involving:

📏 Hooke's Law

⚖️ Elasticity and Force

🌊 Wave Motion

🔄 Simple Harmonic Motion

Students would suspend a spring from a retort stand and gradually add masses.

As the load increased, the spring stretched.

Measurements were taken.

Graphs were plotted.

And one of Physics' most elegant relationships emerged:

Extension ∝ Force

 The Classic Hooke's Law Experiment

Before computer sensors and digital probes became common, students investigated elasticity using little more than:

✅ A spring

✅ A metre rule

✅ A set of masses

By measuring how much the spring extended under different loads, students could determine its spring constant and discover the conditions under which Hooke's Law applies.

Simple apparatus.

Powerful ideas.

Springs and Waves

Springs were also invaluable for teaching wave motion.

Long springs could be stretched across a classroom and disturbed by hand, allowing students to observe compressions and rarefactions travelling along the spring.

For many students, this was their first opportunity to actually see a model of a longitudinal wave.

Invisible concepts suddenly became visible.

Built to Be Used

These packets were intended to be opened, emptied and eventually discarded.

They were consumables.

Not collectibles.

Yet decades later, the original labels remain.

The paper packaging survives.

And the springs inside are likely still capable of performing the same experiments they were designed for generations ago.

There is something deeply satisfying about that.

✨ AHA Moment

Before sensors plotted graphs automatically, students watched the spring stretch with their own eyes.

Before simulations animated waves, students created waves with their own hands.

Sometimes the simplest apparatus teaches the most enduring lessons. Not by technology, but by DISCOVERY. ⚖️🌀📚
