I am trying to figure out is how I can make or use a device
that will periodically/somewhat randomly make a load noise,
erratic motion or somehow shock or stun its wearer.
How about a lens hanging on a loop that would randomly focus
sunlight on the skin that stings the wearer when they are
A liquid crystal mood earring that spells out the words “Hit me
here” when the wearer’s body temperature drops.
Earrings with sizing beads that snag on clothing. Earrings with
sizing balls that snag on clothing.
Earrings that look like African killer bee queens.
Seriously, for reliability this is probably a situation for some
type of microelectronic device.
