Oculus VR
Although it's still a bit buggy, VR has become pretty popular. It's still a super expensive gaming system but it's pretty worth it if you know what you want to do with it. Yes, it looks a bit silly, but that's the price to be immersed in the world of virtual reality!
23andMe
Taking an at-home DNA test became a trend in the late 2010s all thanks to 23andMe. Even though a lot of people think that it's the governments way of getting your DNA into a database, it's still fun to see where your ancestry looks like. Now you can really say that you're "20% Italian" and actually mean it!
