That's. . . a big pile of Boomex, all clumped around a live detonator.
Oh, the detonator isn't live. It's on standby.
I would need to push the red button on this actuator to make it live. But I'm going to push the green button which will make that pile of Boomex and the detonator go inert.
Nobody told me I was red-green colorblind. When did that happen?
