Lorry Trailer Simulation?!?

Sorry if this is formatted wrong or in the wrong place.

Hi! I want to render the contents of a lorry trailer falling out onto a free way (That cliche thing from every action film ever)

However I’m not sure how I can make the pipes on the trailer stay secure until I need the simulation to happen?

I would like it to look like this:
Fast and Furious 7 End Battle Scene
However in my case the trailer wouldn’t be going sideways. The pipes would fallout on the lane next to the truck.

I’m aware of the basics for making things fall. But how to keyframe it so that they fall when I need them to? Thanks!

Hi Andromeda4482,

set the pipes as rigid body and animate the gravity in the scene tab.
