It is a given fact that children love glitter a lot. There is not a child in this world that would choose any other activity above doing literally nothing with glitter in hand. Children love the sparkling sensation that glitter has and like sticking it to different surfaces and literally throwing it around to enjoy a good laugh every once a while.
While you may like your children playing around with glitter, clearing away the mess when they are done is a really big hassle. Glitter can be a pain in the bottom to clear and you are risking becoming all glittery yourself if you don't act smart. The right way to move on with this process is to use a lint roller on surfaces that have glitter scattered over them. The roller would pick up all the shine.
