Abstract
A vehicle shows a vehicle bumper (9) having a first member (10) and a second member (11) connected to a vehicle. Low viscosity liquid (12) is trapped in between members (10 and 11) and on impact of member (10) with an obstacle a frangible membrane (13) can burst causing a high velocity liquid jet to be expelled through channel (11a) thus dissipating the impact energy.
