Spherical Conductor for Electrostatics Glass Dishes & Jars_Glass Crystalizing Dishes preferred over iron or nichrome

preferred over iron or nichrome because it contributes no color of its own to the flame

showing how inclination shifts from horizontal at the equator to vertical at the poles

One-ohm 5W wire-wound fixed resistor enclosed in an ABS module with 4mm sockets

bright illumination for specimens on scopes without built-in lighting

250mL bottle of indicator oil formulated for the PH0150A Boyle's Law Apparatus
