Be sure to wash your Pringles can first thing. Let it dry, and then you can work on your kaleidoscope. Nail a hole through the bottom (metal) part of the can. This is the part you will look through when your scope is finished.
Now that the inside is covered, you can cover the outside of the can. This holographic paper had a sticky side, so I peeled the back off and secured it to the outside of the can. I did not do that on the inside, because it would be too difficult to smooth out the sticky part. Tape is enough to secure the paper on the inside.
You can also add some gems to the end of the can where the lid will go. Cut out a circle of the wax paper and tape it to the outside of the lid. Place the lid back on the can, and your kaleidoscope is finished!
By looking through the kaleidoscope while facing light and turning the lid, you will see the gems reflecting off the holographic paper inside the can. This creates a kaleidoscope effect.
