Perfect for the kid of someone you don't like very much is a Rock Tumbler.
Most kids who receive a rock tumbler want to turn that sucker right on and polish up some precious stones. The tumbler makes a ton of noise for weeks, eventually gets turned off, and then the grit + rocks harden into cement. A waste of time and energy that creates an awful racket!
This rock tumbler is cheap, so you don't break the bank pissing off that brother-in-law you can't stand.
