The "Village"

1. Examine the explosive and read the instruction sheet from the Trading Post.
2. You'll need a timer and a detonator.
3. You can get a timer from the PX dispenser. See that question for details.
4. There's a detonator in the storage room on Level Two. See the detonator question for more details.
5. You also need to drill a hole for the explosive in whatever it is you want to blow up.
6. Since the explosive is the width of a pencil, the small drill bit won't make a wide enough hole. You'll need to use the medium bit or the large bit.
7. If you want to blow up anything that isn't near the airlock, you'll have to keep the explosive from melting. See the previous question.
8. To blow something up, put the explosive in the drilled hole, attach the detonator to the timer and the explosive, set the timer, and leave the room. Now you have to figure out what you should blow up!
