A cool video showing how to use your smartphone to create a 3D hologram.<br /><br />In the video, which was created in Macedonia on Friday, a man first cuts out pieces of an old CD case and uses sticking tape to form a prism-shaped lens.<br /><br /> He then places the prism over the screen of the phone and plays a video of a butterfly and a beautiful hologram appears, appearing to float in mid-air.<br /><br />++MUSIC IS ROYALTY FREE++
