Introduction: Flaming K'nex Spinner (Of Death!)


This is a neat idea I had, where you light candle at both ends then spin it lightly so that as the candles melt separately they try to balance by spinning.

Made out of k'nex!

Step 1: Parts and Tools

You need;
Tin foil,
a tall candle,
a lighter,
a long, thin, straight nail,
a knife,
a cutting board,

and
4 gray k'nex pieces
2 Red quarters,
32 purple quarter-spheres,
4 half-moons,
16 half-sphere,
2 circles,

6 short green rods,
45 short white rods,
30 blue rods,
4 yellow rods,
12 orange rods (with the little separation at each end, though normal red rods would work).

Step 2: Sides


Build two of these, the photos should be clear enough.

Step 3: Connect

Once you've built both sides, add these nine rods onto one then connect them together like so.

Step 4: Tin Foil

Spread some tin foil on the base so that when the wax drips it won't get all over your floor/table!

Step 5: Prepare the Candle

If the wick is not exposed on both sides of the candle, cut off one end and sharpen it so that the wick is usable.

Then, put a nail through the middle. Be careful that it is straight and try not to break the candle.

Step 6: Light!


Light one end whilst holding the other, then light the other end.
You may have to hold it flat for a while so they really get burning...
After about sixty seconds, spin lightly

    What is its use?

    You light the ends on fire, and it starts to move on its own. It's cool.

    It moves on it's own when it's lit? I'll have to try that sometime; that sounds awesome.

    Yeah. Look around on youtube, you really want it to be as light as possible with minimal friction. If you watch the attached video "Spinner.mp4" you'll see what it does :)

    Did you stay up all night thinking and working on this idea? That would make this project complete.

    Just a few hours of trial and error ;)
    if you look in the pictures of it inside on a tray, you can see we replaced the bent nail with a smoother, straighter one.

    Fun project; most of my projects are trail and error, too!
    (btw, my original comment was a joke on "burning a candle at both ends")
