Faraday forcing of high-temperature levitated liquid metal drops for the measurement of surface tension

Sample images of levitated Zr sample at 1800？°C during Faraday forcing experiments. The diameter of the sample in the absence of any continuous forcing was 2.222？mm. Maximum disturbance caused through the application of continuous forcing a below the resonant frequency (180？Hz), b at the calculated resonant frequency (185？Hz), and c above the resonant frequency (191？Hz). A video accompanies this study that shows dramatic deviation from the spherical shape at the resonant frequency and the decrease in this deviation both before and after the resonant frequenc
