A new Japanese bra unhooks only for true love. This is pretty tame, but due to the sensitive subject matter, I’ll disable the link:
There’s a great video embedded in the story that can also be seen here:
This is the mood ring for the 2000-teens: "The newly developed Japanese bra is connected to a smartphone app via Bluetooth. It’s clasp will only open when in-built sensors in the lingerie sense true love, i.e., when the user’s pulse rate reaches the ‘True Love Rate’."
Oddly, it’s not actually for sale to the public … yet. But you can win a chance to test it out.
