Viscosity Materials for Density Lessons

Viscosity is the measure of the "thickness", or "fluidity", of a liquid. When turned upside down, the colorful viscous liquid in Soother Ooze Tubes takes about ten minutes to flow through a large opening in the sealed plastic container. By timing the fall of a sphere through different known grades of oil, the student can construct a time vs. viscosity graph. The Speed of the Bubble Tube Set consists of three 22-inch-long transparent plastic tubes containing colored fluids with three different viscosities.
