Holographs $$$ 🎓🎓 💪

Holographs are 3d pictures made using a laser on film.  You shine the right light on the film (doesn't always have to be a laser light), and you get the 3d picture popping up.  Holographs are actually better resolution than normal printed photos - theoretically you could take a holograph of a leaf and use a microscope to view the nucleus of bacteria on the leaf. 

All you need is a dark area to take the holograph, the right laser(s), the right film, and a bit of knowledge.   And a good subject for the holograph.  I used a small fire hydrant I made in a glassblowing class.

It is a bit expensive - both to learn how to do it and to set something up in your home.   It's not that hard to do any one kind of holography, but there are a lot of techniques and variations to learn.   So to truly master it, you can easily spend thousands of dollars.   Also, you are working with film and chemicals, not merely computer chips, so there are quite a few expendables you need to purchase.   But it takes no muscle.

Holography trends male, and older.  Yes, kids like to view holography, but it is just hard enough to deter all but the most determined teenagers from trying it.   Classes are very small - you work in a dark room.  That's another reason why it is so expensive.
