Completely safe to touch and handle, simply complete the circuit by touching both electrodes at the end of the stick simultaneously.

A super-sized slinky for engaging classroom physics demonstrations.

Measuring in at 11cm long and 7.5cm in diameter, this coiled beast can be stretched to almost 10 metres long! Making for impressive light and sound wave demonstrations when stretched and flicked.

Long, but light enough for practical experiment use. Observe the Slinkys unique ability to walk down steps or sloping surfaces, and learn valuable concepts in force and motion.

Made from high quality steel, this spring is electroplated to prevent corrosion and improve its lifetime wear. The quality steel construction also ensures that the original shape is regained after stretching.

Bring your physics demonstrations to life with this giant spring.

Age: 8+

What You Get

1 x sturdy giant spring. Measures: 11cm long and 7.5cm in diameter, and can be stretched to approximately 10m long! Made from steel, and electroplated to prevent corrosion.

How does it work

The slinky demonstrates concepts in force and motion by its ability to "walk" down steps or sloping surfaces. The slinky slowly flips end over end - stretching to reach the next step down before reforming, then stretching again. Gravity and the force of the slinky's own momentum is involved in its movement as well as potential and kinetic energy.

Use the slinky to demonstrate light and sound waves by stretching it between two students, and flicking. Observe the vibrations travelling, as each coil hits the next coil and passes its energy via vibrations. Create waves (similar to ocean waves) to demonstrate light waves.

History of the slinky

The Slinky is a classic American toy, which is rumoured to have sprung out of Pennsylvania in 1945 (pun intended)! The slinky's creator was a retired Navy engineer who initially thought the bouncy coils would be useful for supporting sensitive instruments onboard rocking ships. But sadly the Navy had no interest in James' springs... but his wife Betty had a better idea for these bouncy springs! She decided to brand her husbands cool invention into a fun new toy, and even came up with its catchy name; the Slinky.
