Reaktyvinis valties žaislas
„Gelsonlab HSTM-074“ švietimo mokslo žaislų reaktyvinių valčių eksperimentas
Reaktyvinis valties žaislas uses the motor to drive the impeller to rotate at a high speed, which produces a centrifugal force, which makes the water in the cavity eject from the water nozzle, and the hull moves under the action of this reaction force.
