Beside the typical alarms, cameras, guns and knives, what kind of practical home defense ideas do you have?
For example, I know that rock hard frozen cornish game hen can knock an intruder out cold if you somehow make it to the freezer - they fit nicely in the hand and you can chuck them pretty good. Rice or beans thrown on the smooth kitchen floor in front of the bad guy becomes a slippery issue. Spraying Pam in the eyes also deters someone for a bit. Same as a handful of flour or sugar in the face.
The kitchen is the best place to be, I tellya.
