Jim:
That's the video!
The second half though, I never saw before.
Now that I see that half, it's quite obvious it's fake.
If you look closely, when they move in for a closeup as they pull off the heat sink, you can see smoke in the background, coming from beneath the plywood. And when they show the more distant shot in the second pass, again, you can see the smoke before it blows up. But even more damning, is that you can see someone's arm moving beneath the plywood, as if they are trying to flick a lighter quickly at the fuse and pulling their arm back and then trying again when it fails to light.
