Metal Slinky, Helical Spring
Metal Slinky, Helical Spring (Product Code: SLE/PHY/243) is a steel helical coil spring used to demonstrate different types of waves in school and college physics lessons. Its 75 mm coil diameter gives a wide spring that is easy for a class to watch as a teacher or two students send pulses along it across a bench or floor. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Metal Slinky Used For?
Stretched out on a smooth floor or long bench, the spring shows both main wave types. Pushing one end back and forth sends a longitudinal wave of compressions and rarefactions along the coils, while flicking the end sideways sends a transverse pulse. Students can watch pulses reflect from a held end, see two pulses pass through each other and set up standing waves by shaking at a steady rate.
Timing a pulse over a measured length gives a simple estimate of wave speed, and changing the stretch shows how tension affects it, which makes the spring a good hands-on start to any wave motion unit in school. Tie a short piece of coloured thread to one coil so the motion of a single point is easy to follow. Avoid over-stretching or tangling the spring, and store it closed so the coils keep their shape.
What to Specify When Ordering
- The number of springs: one for demonstration or one per pair of students.
- Whether you need the closed length confirmed before ordering, as the listing does not state its unit.
- Whether other wave apparatus, such as a ripple tank, should be quoted for the same topic.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this Metal Slinky, Helical Spring. The springs are produced at the company's own licensed factory in Saha, Ambala, Haryana, India, and supplied directly, not through a trading intermediary, to schools, colleges, distributors and importers. Enquiries about replacements or repeat quantities are answered by the manufacturer itself, and company details are on the ScienceLab profile page.

Frequently Asked Questions
What types of waves can the Metal Slinky, Helical Spring demonstrate?
The Metal Slinky, Helical Spring demonstrates longitudinal waves, by pushing and pulling one end along the spring's length, and transverse waves, by moving the end sideways. It also shows pulse reflection, superposition and standing waves when shaken at a steady rate.
What is the Metal Slinky, Helical Spring made of?
The Metal Slinky, Helical Spring is a helical coil made of steel with a coil diameter of 75 mm. To keep the coils even, handle it within a normal stretch during lessons and store it in its closed position afterwards.
What is the closed length of the Metal Slinky, Helical Spring?
The product listing gives the closed length of the Metal Slinky, Helical Spring as 100 without stating the unit. If an exact closed length matters for your lesson plan, ask ScienceLab through the contact page to confirm it before ordering.
Who manufactures the Metal Slinky, Helical Spring?
The Metal Slinky, Helical Spring is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer with its own licensed factory in Saha, Ambala, Haryana, India. Schools and dealers buy it factory-direct, with quotations issued by the manufacturer.
How should students use the Metal Slinky, Helical Spring safely?
Use the Metal Slinky, Helical Spring on a clear floor or bench with one student holding each end firmly. Never let a stretched spring snap back towards anyone, avoid over-stretching, and ease out any kinks gently before storing the spring closed.
Can the Metal Slinky, Helical Spring be ordered for a whole class?
Yes, the Metal Slinky, Helical Spring can be quoted in class quantities for schools, colleges, dealers and importers in India and international markets. Mention how many springs you need and your delivery location when you send the enquiry.
