Step 1: Gather your parts
1. A square aluminum tube 1/2 in in size any length over 12 inches long
2. some cardboard
3. an old/cheap tripod
4. aluminum foil
5. tape of some sort, i used
6. plastic cone*
the cone is optional, you can use all cardboard for the cone part if you wish
Step 2: Put the stuff together
Then make another cardboard holder to keep the tube centered inside the cone
Use whatever tape/glue you have to secure the cardboard.
Cut one part of the cone out so that it sits flush with the camera lense. This will differ with your camera/tripod setup.
Make a bridge out of cardboard to put between the legs of the tripod and the metal tube. I used zip ties to keep it there, but you can tape or glue it.
To keep the kaleidoscope in place i wrapped tape around it on both sides of the bridge
Step 3: Take Pictures!
Align the camera lens with the end of the tube and start taking some pictures!
I suggest some flowers, or a brick building, the siding on a house is interesting too, anything bright, just don't point it at the sun, that's just not smart...
