28-Piece Visible Ray Geometrical Table Top Optics Set Category_Chemicals Three 1W resistors of different

Three 1W resistors of different values on a single base with six 4mm terminals

sized for large-scale demonstrations of elastic potential energy and simple harmonic motion

the polished 90-45-45-degree faces redirecting light at right angles for total internal reflection demos

Compact 150mm black 4mm-stackable lead with nickel-plated split-hollow pins

sized for high-turn-count windings where each turn adds little diameter to the coil core
