N2 - Water-model experiments of lance-jet impinging on a liquid free surface were carried out. A cavity was formed on the free surface by the impinging jet and unsteady behavior of the cavity was observed by continuous shooting. Cavity depth and diameter were measured from the photographs. The time average of cavity depth is consistent with the semi-theoretical relation proposed by Banks & Chandrasekhara, and the time average of cavity diameter is consistent with the estimated formula by Tanaka & Okane. The standard deviation of the cavity depth is roughly 10% of the time average of the cavity depth, while the standard deviation of the cavity diameter is roughly 15% of the time average of the cavity diameter.
