For studying reflection

Bobbin-wound transformer coil with 4mm panel sockets

its sectioned carburetor and fuel supply exposing the compression-ignition cycle to a hand-cranked turnover

3V 2A AC filament line for cathode-ray experiments

Hand-driven Newton's color disc that spins seven painted segments fast enough to merge into apparent white through persistence-of-vision and additive color mixing

Carbon Electrode, 100 x 20 x 5mm Subcategory_Pitchers For studying reflectionSolid carbon electrode bar that conducts current without participating in electrochemical reactions, isolating ion behavior in electrolysis and voltaic cell investigations.
