Wave Form Helix, 10 cm Closed Height

Closely wound steel helix for studying wave behavior.

• Wave form helix
• 7.5 cm diameter
• 10 cm long when closed
• Up to 3m in length when fully stretched

This is a Wave Form Helix that can be: 1) used as a scientific instrument to measure a wave function (it actually has a higher spring constant than the classic toy); or 2) unleashed down a wicked set of stairs. It has a 7.5 cm diameter, 10 cm long when closed, and up to 3 meters in length when fully stretched.
