Spectrum Tube Holder Light & Optics_Color providing lightweight projectiles for collision-and-ramp

providing lightweight projectiles for collision-and-ramp experiments where steel or glass would carry too much momentum or break on impact

and core layers detach one by one for geology instruction

this 18 SWG bare constantan wire on a 125g reel relies on the alloy's low temperature coefficient

Fifty-turn 4A coil for the demountable transformer

and a semi-circular glass block fill this tabletop optics kit
