Non-persistent landmines?
I like the idea but Id like to hear more. Old landmines from previous wars are still blowing people up (or so I hear) but how do you make a mine that deactivates after a period of time?

This website FAQ re landmines provides look back to the issue in 2004 when the pres changed landmine policy. Back then the mines could "blow themselves up" any where from 4 hours to 15 days after implacement.
