5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Simultaneous AC and DC output

Simultaneous AC and DC output on this low-voltage power supply

with identical volumes across specimens for direct mass-density comparison

Turning the hand crank walks students through every stage of the 2-stroke gasoline firing cycle on a 14-inch model

paired with electroscopes and pith balls in classic electrostatic-charging investigations

sized for ripple tank and bulb-driven physics demonstrations

5-Material Equal Mass Density Set (Aluminum, Brass, Nylon, Acrylic, PVC) Metal Labware_Metal Bases & Rods Simultaneous AC and DC outputEqual mass density set in aluminum, brass, nylon, acrylic, and PVC, the shared mass isolating volume and density as the distinguishing variables across metals and polymers.
