Have you ever play with a pinhole camera that is a simple camera without a lens and with a single small aperture — effectively a light-proof box with a small hole in one side.
It can be easily made with an empty pringles chip can
(See how to make it on http://www.exploratorium.edu/science_explorer/pringles_pinhole.html)

Now you can have glasses with poinhole lens and see the twirling images in an easy and fun way!!!

Here is our upgraded version of the pinhole lens.

Step 1:

Material needed: 2 pringles’ pinhole lens cams (see last posting for the instruction), ruler, tape, unused big glasses frame, cutter, empty box (here we used shoe box), fabrics for cover.
It's more a kaleidoscope than a pinhole lens, thanks to the distance between the pinhole and the eyes, and it would be far better to embed the video in the Instructable, rather than just posting a screen-shot and a link.<br><br>(It is pretty cool watching the images of the outside world projected around the inside of the tubes.)<br><br>
<br> You don't explain this very well. It's a dual miniature camer-obscura type thing and I want to build one.<br> Try to emphasise how great it is to stare into this.<br> <br> L<br>
