Interesting only because most people already have those vaguely described items in their house.
Only exception might be "canisters" of fuses??
I think I have all of those things around my house and garage:
a metal pipe: Yes, I have metal pipes under my sink. One is for hot water, one is for cold water, and one carries away the water from the sink.
canisters of fuses: I have plenty of fuses for my house, garage, truck, and bike, but no canisters. Is it safe?
a lighter: I have a long-barreled assault lighter, to light my charcoal grill.

I also have several cigar lighters.
a digital scale: In my bathroom, accurate to 300 lb.
a plastic spoon: I found a box of 24 in my cupboard. 24!
coils of metal: Four of them on my electric stove.
several pounds of chemicals: Laundry detergent, kosher salt, Oil-Dry, lawn fertilizer, a big bag of Epsom salts.... yes, I have "several pounds of chemicals".
It's only a matter of time before the NSA reads this post. I'll go pack a bag and wait for DHS.
