Cut a straw to 2/3 the length of the chop stick and slide it on. Add an electrical tape flag at the bottom of the stick to prevent the straw from sliding off. The straw will act as a bushing allowing you to hold the Zoetrope while letting it spin freely.

Finally, add a tape flag on the back of the chopstick to prevent the chopstick and disk from falling out and you have a finished Stroboscope. To use, point at something moving, close one eye and look through the eyepiece with the other while spinning the disk via the chopstick. We found twisting the chopstick in front of the disk is the most effective way to get the disk spinning fast, and that trying to spin the shutter disk itself tends not to work well and will eventually break the stroboscopes.

Now you are ready to begin assembly. Take the short tube sections and remove the inner tube from the outer. Place a piece of plastic bag (at least 3” square) over the outer tube and then push the inner tube inside. This should stretch the plastic over the end of the tube section and will function as a diffuser in projection mode and a screen in camera mode.
