DESCRIPTION:Liquid foams are\, amongst other usage\, used to mitigate shoc
 k waves during mine-cleaning operations due to their excellent ability to 
 absorb energy. However\, the origins of this important property are still 
 not well understood. We use a shock tube to send a shock wave on a foam sa
 mple with controlled liquid fraction and bubble size. We record images wit
 h a high speed camera and pressure signals through the sample\, giving inf
 ormation about the wave propagation and attenuation\, the foam displacemen
 t and the destroyed area.\n
