This hologram can also be eaten
Abu Dhabi: Scientists at the Khalifa University in the United Arab Emirates have developed a hologram sticker that can be eaten and digested.
It should be noted that in recent years, the use of stickers such as “3D holograms” in the identification of various “real products” has been increasing as their price has been steadily declining.
So far, holograms have been printed on paper, wood and plastic, but there has been limited success in making holograms on chocolate in food and beverages.
