"Tubes"

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

The Air Core Solenoid is perfect for induced magnetic field studies.
