Splashes from underwater explosions [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949 The splashes from the underwater explosions of 1 and 10 lb. charges of P.E. no. 2 and Nobel’s Explosive ‘808’ at various depths have been photographed with cine-cameras. The experiments were carried out in a sheltered pond which enabled the surface phenomena to be studied in greater detail than has been done hitherto, and a number of new ...
