More than anything else, Americans wanted to know how to make slime in 2017.
You read that right. "How to make slime" was the most frequent "how to" Google search this year, Google Trends announced.
It came ahead of searches such as "How to make solar eclipse glasses," which peaked around the August solar eclipse; and "How to buy Bitcoin," which is the current flavor of the month after the digital currency's recent surge in value (though not great for the environment, apparently).
Another faddish search was "How to make a fidget spinner," the fifth most searched for "How to" term of 2017, with DIYers looking to make their own versions of the handheld gadget.
And following the Equifax data breach revealed earlier this year, "How to freeze your credit report" was the seventh most popular search, as the tens of millions of affected Americans scrambled to protect their personal data. (We wrote about how to to do that, if you're still wondering.)
But seriously, slime?
Yep. It became an internet sensation at the beginning of the year, believed to have mainly originated in the Far East.
Soon enough, millions of social media users were sharing pictures and videos of their DIY slime on Instagram and YouTube.
It's not the stuff you'd find on Nickelodeon, but what NPR describes as a more "viscous and elaborate" concoction. The craze even prompted the American Chemical Society to publish a guide and video for how to make the stuff.
To create your own, all you need is some borax – a laundry detergent supplement – mixed with glue and water, then stirred with a popsicle stick.
DIYers add food coloring, beads and glitter – basically whatever they want to give it a funky look.
The Daily Telegraph reports some parents have been using alternatives to borax, such as cornstarch or other laundry detergents, amid warnings from health officials that exposure to too much borax can damage fertility, as well as be a mild skin irritant.
While being fun to make and play with, some of the slime videos on YouTube market themselves as relaxation tools.
