A YouTuber, "Mrwhosetheboss" just released this freaking awesome video, which explains how you can make a hologram -- a virtual 3D object that actually floats in the air -- using just your smartphone and a few things you have lying around the house.
Here's what you'll need:
- Graph Paper
- CD Case
- Knife/Glass Cutter
Check out the video for a step-by-step guide.
Once you put it together, here are a few videos you can play on your phone to project the holograms right from your screen. Show it off the next time you have friends over. It's a neat little party trick.
