I found a fascinating read last night about a very interesting liquid land mine concept using Astrolite. Astrolite is the only known liquid explosive that can be used to wet the ground and remain viable to detonate a few days later, even after rain on a previous day (see attached picture). Astrolite G can be made from a reaction of 2 parts by weight ammonium nitrate with 1 part by weight of anhydrous hydrazine (done in a fume hood due to the copious amounts of ammonia gas evolved), while aluminised versions also exist, e.g. Astrolite A-1-5 with 20% by weight >100 mesh aluminium powder. Astrolite - Wikipedia, the free encyclopedia Does anyone know if these were actually used by the military at any degree or if this application is in reality just a technological curiosity? Presumably not used by the UK in recent history, because of the Ottawa Treaty. Hydrazine of course is extremely toxic, costly and difficult to procure, the toxicity sufficiently so that even national space agencies get twitchy around it. So don't worry - Terry won't be getting his hands on this!
