It is an action movie that I watched when I was a kid (sometimes around 2006 to 2010). It may be a movie with Jackie Chan, but I may be wrong. The only thing I remember is that at the beginning of the movie, some guy goes to a laboratory. Inside the laboratory there is a glass container filled up with some liquid. In the liquid there is a rock-like object that floats around faster and faster. Then the guy put that object inside a metal capsule and then in his backpack and goes inide a truck and starts driving. While the guy drives the truck, the object starts moving inside the metal capsule faster and faster and soon it explodes with a very huge explosion. I don’t remember the rest of the movie.
You remembered well, it is a Jackie Chan movie. Its original title is “Ngo si seoi”, its worldwide English title is “Who Am I?”, but it is known as “Jackie Chan’s Who Am I?” as well:
