Abstract The Berthelot tube has been used for many years to study the behaviour of liquids under tension until tensile failure occurs and the liquid cavitates. Whilst the liquid is under tension it exists in a doubly metastable state, being both superheated and supercooled simultaneously. Reported herein is the first study of the cavitation bubble dynamics upon tensile failure of water in a Berthelot tube using both static and dynamic pressure measurements and high speed photography. Also presented is the first photographic evidence of ice formation from supercooled water which is simultaneously superheated by tension. Introduction Despite great interest in supercritical fluid processing [I], little attention has been paid to e
