Metal Slinky, Helical Spring, 100mm Closed Length (Each)

A scientist's version of the classic toy! (With a higher spring constant)
Can be used as a scientific instrument to measure a wave function and for demonstrating a variety of physics concepts
Unleash the helix down a wicked set of stairs for an exciting display
Measures 4" when closed and 3" in diameter
Stretches up to 3 meters in length!

Can be used as a scientific instrument to measure a wave function (it actually has a higher spring constant than the classic toy)
Great for demonstrating a variety of physics topics including potential and kinetic energy, Hooke's Law, energy of motion and more
