Plastic Wave Apparatus for Longitudinal and Transverse Motion Base_Octagonal and gas control on natural

and gas control on natural gas for high-temperature chemistry heating applications

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

and phosphorus for organic-chemistry work

Aluminum-handled collecting net swings lightweight through tall grass and air sweeps for classroom field trips and introductory entomology sampling work

supporting small-feature eye anatomy teaching

Plastic Wave Apparatus for Longitudinal and Transverse Motion Base_Octagonal and gas control on naturalPlastic bodied wave apparatus with eccentric discs that drive metal rods up and down as the handle turns, exposing the longitudinal and transverse components of wave motion mechanically.
