The fine folks at Bleach Eating Freaks have published instructions om making a miniature claymore mine out of ordinary office supplies. It reminds me of the stuff you’d find in the old Anarchists Cookbook. I wouldn’t recommend making this, as it looks like it could cause damage to someone’s eyes. Nevertheless, the design is quite beautiful.
