Craftsman Commercial - Drilling In Reverse?
I was watching Ice Road Truckers last night, which is sponsored by
Craftsman, so they kept running this commercial for one of their cordless tool lines. They show one clip where the guy is drilling into a piece of wood attached to a tree - steps to a tree house maybe - with a wood boring bit. Maybe it was an optical illusion, but I'd swear the drill is running backwards - counter clockwise. I rewound my DVR a bunch of times, and ran it it slow motion. It sure looked to me like the bottom of the bit was coming up and the 3/8" marking was going away from, not coming towards the viewer. Has anybody else seen this? |

Might be why they call it the 'Wagon wheel' effect. In a nutshell it has to do with permanence of vision, frames of film, and optical tricks our mind plays on us.

Did you consider the fact that the guy is an actor. The drill may actually be turning backwards because the actors and directors don't have a clue. I know, I'm being fecesious (sic). TDD |

TDD Yup facetious. Happens often with films and TV because the picture we see is actually some 25 to 30 snapshots (or frames) per second. For example, with TV, older TV anyway not necessarily digital and HD, it it is presented to us so that alternate lines are scanned and viewed first each frame and then during the same frame it goes back and does the intervening lines. In fact any thing rotating may appear to be either going forwards or backwards. Doesn't mean a thing. But maybe the hole had been drilled by the fifth take and they are now on their 15th and the actor is basically instructed to "Here; hold this and pretend you are drilling. And oh, by the way look happy about it ......"! :-) |

Ah, the strobe light "stroboscopic" thing. When the
frequency of the camera shutter is a little different than the frequency of the drill (in RPM) the drill can appear to be going slowly forward.... or slowly backward. -- Christopher A.

You eventually have to come out of the hole. If you follow the sequence of the clip, he inserts the battery and then begins to drill into the wood. |

Would the wagon wheel effect still be present in a slow motion viewing of the object? |

What we have been discussing is 'timing'; as each part of something rotating (in the case of wheels it could be identical-looking spokes for example) comes into each frame of a film or TV picture. It may then appear to be ahead of or behind the one seen in the preceding frame. So the item my 'appear' to rotate either forwards or backwards. Mirror or not; viewing film is a matter of the optics used and how the film is then projected onto either a screen or into a TV transmitter. It was possible in some film installations, for example, to adjust the focal length etc. of the projector so that the picture could be seen reversed and/or perhaps upside down! |

I don't know-- but I was playing with my new toy [Bosch impact driver as recommended by John in another thread] today and in full sun, at just the right speed, if you stare at the bit it looks like it reverses direction. I know it didn't because the screw kept going in. Jim |

You obviously do _not_ know what strobing is or you wouldn't be going on this way. I notice you make no reference to do any google on it. I did and found pages of it including clips. True most of the clips do involve wheels. Your example of the screw, the chuck etc. all have 'wheel spoke' like things, the screw, the chuck key fingers (if it has them), any knicks, burrs, chips, etc on the bit. Harry K |

Oh, I thought you were done telling us that you KNOW the explanation for something that you admit to NOT HAVING SEEN. Yes, the various parts of the drill mechanism have regular features that could be analogous to the spokes of a wheel. But to suggest they could all exhibit the "strobing" at the *same RPM* is nothing short of preposterous. There is absolutely nothing blurry about the commercial. The drill is operating at a very low RPM and the moving parts are in crisp focus the whole time. The video is shown in mirror image, and that's all there is to it. *Anyone* who has ACTUALLY SEEN the commercial would agree. |

That's because there is no other explanation for daylight. However, regardless of the existance of the "common effect of strobing" there also exists a number of other reasons for the bit to appear to be rotating backwards, the obvious one being that it actually is rotating backwards. There's also the possibility of the film being a "mirror image" of the actual event. I'm not claiming that the cause *isn't* the "common effect of strobing" - although I seriously doubt that in this case it is - I'm simply pointing out that your argument for not needing to see the commercial based on the fact that the sun causes daylight is flawed. |

Let's say there's 4 repeating features on the screwdriver bit (the square sides), 3 chuck fingers, and 10 grooves around the outer diameter of the chuck. The strobe couldn't make them all appear to turn backwards at the same RPM. Oh, yeah, there's also the threads on the drywall type screw that are turning backwards. |

Well of course they all rotate at the same speed, they are fixed to one another. In real life they are also rotating at the same speed so why wouldn't they in strobe effect? The fact that some of them are farther out from the axis does not effect their position when the strobe hits. Somehow you seem to think that everything is rotating at different rates You could build a wheel 6' in diameter and tie rags aroudn the spokes at diffent distances from the axle and they would all show the same effect. ..

Harry K- Hide quoted text - - Show quoted text - "Occam's razor comes into effect." If you're going to play the Occam's Razor card, then the strobing explanation should be the one that is thrown out. "When you have two competing theories that make exactly the same predictions, the simpler one is the better." What's simpler: That the drill is actually running in reverse or that the strobing effect is the cause? I submit that the drill actually running in reverse is the simpler explanation - IFF we are ranking the possible reasons for what we see in terms of their complexity. What's simpler: "Press this button and the drill spins one way or the other." or "The 'stroboscopic effect' is explained as follows..." BTW: Smitty Two is not talking about the same commercial - or at least not the same segment - as I am. The clip I saw was a wood boring bit, not a drywall screw. I have not been able to find an on-line copy of the commercial. BTW-2: I'm not sure if one of my earlier questions has been answered, so I'll ask it in a slightly different manner. First, I know that the stroboscopic effect exists; I've seen wheels "turning backwards", so I'm not questioning the existance of the "wagon wheel" effect. That said, let's assume that the perception of the drill turning backwards *is* caused by the stroboscopic effect. Is the effect actually captured on film/digital storage or is it just preceived by the viewer when watching the clip? The reason I ask is that, as I have mentioned before, when I run my DVR in frame-by-frame mode, it still appears that the drill and bit is rotating in reverse. If the effect is captured on film, then obviously we would see it while watching the commercial. However, if the effect is really just a "perception", whether in real life or while viewing a commercial, then wouldn't one have to assume that the fact that it is seen even when viewed frame by frame means that there is some other explanation? |

Harry K It's an RPM (revolutions per minute) vs. RPM (repetitions per minute) thing. Yes all the parts rotate at the same actual RPM. But it is the repetition of a regular feature (spokes) that causes the wagon wheel illusion. If the drill is really turning at 100 RPM, then in my example above, the frequency of the features going by your eye will be 400, 300, and 1000 repetitions per minute. So as far as the wagon wheel effect is concerned, the various parts of the drill are turning at different RPMs, i.e. they couldn't all exhibit the effect at the same actual RPM. |
