I could make a dozen lethal traps from the household items in our office, but if the burglar is harmed by one of them, I'd be facing serious charges.
I would never give lethal trap suggestions to be placed in a school or your own place of work as far as you know. Mentos Grenade is just a tablet of Mentos, some thread, a lighter, and a Diet Coke. You tie up the Mentos, wrap it around the opening in the Diet Coke so that when you close it you can't see it, and use the lighter to burn the extra thread and seal the bottle so it looks new. Obviously don't tip the bottle. It pretty much makes a volcano of soda.
