You may recall that we reported on a website that will send glitter to your enemies.
It's been an overnight sensation, so much so that the owner of the website has had to sell the idea because he's been completely inundated with requests.
Seriously.
Anyway, since the site has launched, thousands of orders have been placed - but this is the first video of the end result we've come across.
According to YouTuber edamame, their father made a point of opening their mail - which is not sound, obviously.
So how do they deal with this invasion of privacy? GLITTER BOMB.
