Knows hose?

An expert’s analysis of an electrical fire on a boat involved a “‘hose test,’ in which he directed water from a garden hose onto the boat’s wet bar and tracked where the water ended up.” Unfortunately for him, because this work was “meant to be a simulation or re-creation of what actually happened, it must be performed under ‘substantially similar conditions'” to the fire, and it was not: “Plaisance’s videos did not contain important information about how he conducted the experiment, such as ‘how long the hose ha[d] been running’ or ‘the pressure of the water coming out of the hose.’ Moreover, the video showed ‘a continuous stream of water from a garden hose directly at the junction between the back of the wet bar and the boat’s wall,’ and there was no indication that Gonzalez ever used a hose in that fashion. In fact, as the district court noted, Plaisance did not provide any information about how Gonzalez typically washed the boat.” Similar problems also undermined another expert’s testimony about electrical issues on the boat.
