Make a zoetrope or 20

Zoetrope means Turning Zoo or Wheel of Life.
I developed this kit as a way for kids to learn the basic mechanics of strobing images and get excited about animation. My first workshop was with our local science discovery centre's school holiday program. (Scitech!)
The kit had to be exceedingly simple and quick to make because I had to make at least 30 of them and, when my lasercutting deal fell through, I had to make them in a day.

There are so many variations out there you can really take your pick. This one is really easy to put together.
I had purchased bearings and bolts and all kinds of things that I didn't end up using. Hanging it with thread was someone's stroke of panicked genius that day. It's easy, hands free, and spins for much longer.

Materials!

For the main barrel:
A1 sheet of black cardboard (you can use a smaller one and tape bits together)
  Scalpel/snap blades
Plastic plates (a little more than diameter of zoetrope barrel.. plates normally make for a good grip around the edge)
  Something to punch holes (punch+hammer, drill press, hot wire.. whatever!)
White paper for your animation (can use A1 or smaller strips stuck together)

For the stand:
Wire (>1mm)
  Wire cutters
OR
Sturdy cardboard (2 x A4)
  Knife

Also:
Long ruler
Pencils
Thread
Clear stickytape/sellotape

Step 1: Measure and cut slits

My zoetrope has 13 frames 40mm wide. The slits above the frames are 40mm tall and 2mm wide.
My first kit had 3mm slits; that was too much and the animation was blurry.

This is the most time-consuming part, but if you're only making one it shouldn't take very long.
I had to use slave-labour and/or bribery. 

13 frames is a traditional format.. The number of frames is usually odd. I speculate that this is so that you look through a slit between frames – directly at the opposite frame. In reality, with this kind of kit, you will not notice any difference and can make it as many frames as you want.
13 frames is small enough that kids have to keep their design very simple and can therefore actually complete a loop in the given time.

Great project! My father received one of these from Playboy magazine when I was a kid (it was meant to sit on top of the record player), and I remember my brother and I had hours of fun playing with it, making our own strips to go inside it. I was just thinking about what a great toy that was recently, but it never occurred to me to build a stand to replace the record player - now I can pass this on to the next generation! (Without the Playboy-supplied strips, probably.)

Ha that's an intriguing story. Record player sounds like a great idea. Please do pass it on! It's a wonderful skill for a child to have - pretty versatile for the old abstract thinking as well.

This is exactly what I needed for an activity I'm running soon!

AWESOME. Just explain the different strobing technologies really well and make sure the animations are SUPER-simple. Also, beware the MIND-NUMBING amount of labour involved if you are making a number of them!! Good luck, Kiteman!
