120mL Glass Alcohol Lamp with Metal Cap and Fiber Wick Biology_Microscopy firing a 19mm ball up

firing a 19mm ball up to 10 feet with less than 1cm scatter

and inner ear sections support detailed auditory anatomy teaching at 3x enlargement for classroom visibility

this demonstration electroscope detects and visually quantifies the magnitude of static charges

Heavy-gauge steel inclined plane with built-in vertical

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current
