You probably wouldn't believe it if I told you that you could make a hologram appear in 3D just using your smartphone. Especially if I said all you had to do was pay about $10 for a little plastic piece. But this isn't a scam, it really works!

Check out the video above from Unbox Therapy where he tests out the SmartHologram pyramid and shows how it works. You have to look up a certain kind of video, but when you do it shows up in the pyramid and is totally 3D. It also works on any type of Smartphone.

You can get the device for about $10 on Amazon right now, or you can find instructions online to make it yourself with things you probably already have around your house.

You may not be ready to put on a Tupac hologram concert quite yet, but you're definitely headed in the right direction.
