Wool Cloth for Electrostatic Charging Item Type_Density Cubes & Cylinders holding under at least 100

holding under at least 100 Newtons of separation force after hand-evacuation of the air between them

Steel U-section 170cm track on foot supports

Demonstrates that horizontal velocity is independent of vertical motion by ejecting a ball vertically from a moving aluminum car

where colored liquid in a U-shaped section shifts measurably as air blown through a constricted glass tube creates pressure differences

this apparatus aligns suspended particles in a liquid medium between charged electrodes to reveal dipole and parallel-plate field shapes

Wool Cloth for Electrostatic Charging Item Type_Density Cubes & Cylinders holding under at least 100Used to generate triboelectric static charge by rubbing against glass, rubber, or acrylic rods, this wool cloth is a standard accessory for electroscope and Van de Graaff work.
