The heat from the hairdryer lulls the trunk gremlins into a false sense of security and they become comfortable and drowsy. They are, however, terrified of cats and when they hear the hissing of the compressed air, they mistake it for a pack of angry cats due to their decreased awareness. Enraged, they begin kicking violently in a frenzy outward on the dent, which pops back out.


Fucking *science!

1. Use a thin screwdriver or paperclip to stop the fan from spinning.
2. Blow compressed air into the exhaust vent.
3. Use the screwdriver or paperclip to pull out any mutant dust bunnies that get stuck inside.
4. Done!

Of course, this only works if the fan is somewhat accessible from the outside.

Explanation anyone...?
:?

The combination of the heat of the hair dryer (first) with the extreme cold of the compressed air (second & turned upside down) causes the dent to expand and contract quickly enough that it pops back to its original shape.

Payback is correct, only works on light metal of a flat surface.

Step by step process...
Basic vid, heaps out there to chose from.

I'd be interested also. My base guess is that it has something to do with the metal rapidly going from the heat of the hairdryer to cold from the compressed air -- those cans get frigid if you release a large volume from them. I could be way off though.

^to be clear, macs aren't any easier with this.

White Unibody MacBook :

1 - Remove 8 screws from bottom
2 - Remove bottom case
3 - Blow compressed air into fan
4 - Do the opposite of steps 1 & 2 in reverse order

the only fake thing about this is that they did multiple takes yet the film implies through editing that its all done in one go obvously artistic lisense as it wouldnt realy flow if he cept going up and down.

as for water pressure and people going deep and coming up fast , its only a big issue when you are using compressed air or are going really realy deep.

Surely you have heard the phrase "fake hollywood action crap" that is often applied to things like never reloading a gun or jumping a car off of a fruit stand. You know the part of this video where the guy dives all the way down a 202m deep hole without stopping and comes back without oxygen? It was faked, staged, fictional, false etc.

Saying that some people can't swim is amazingly cruel. The only people who are ever incapable of swimming are the paralyzed or immobilized, and most partially paralyzed folk can still swim. I hope you find a better way to use the word "can't". I am not going to say that you can't!

Dag -

Solar power has and will come a long way since it's conception. Remember this is an industry just coming out of its infancy.

The issue about batteries deals with the storage of the energy produced, not the actual production of energy. The currently most popular energy storage device is the battery (which the technology seems to be advancing every year), but there are alternatives to that including: hydrogen gas (a converter splits water and stores the hydrogen gas for later use - either heat or electricity production), compressed air (some energy production facilities use underground caverns pumped full of compressed air and then covert that into energy when needed), or simply a lack of storage by people that tie to an existing electrical grid.

Dannym is quite correct on the new production techniques have advanced. Currently there is a company that has been able to produce solar powered sheets of plastic. They have taken the advances of nanotechnology and applied them to this field. The conversion rate isn't great, but the cost of production are much less than traditional methods. The idea is that it can be made into siding for houses, roof tiling, etc.

I haven't read about the Thorium reactors. I can safely assume that there have been advances in that field in the last 30 years as well. I will look into that. Thanks for the link. I used to work in reactor plants, but had no desire to continue that work in the civilian world. All the nuclear plants in the US are east coast, california, or stuck in the midwest (and a small one in colorado.) I love the pacific northwest and had no desire to be anywhere else. It just something about the mountains and water... and looking across the water to see more mountains. Part of my soul is here and I'd rather not leave that. Oh yeah, a point - I haven't looked into newer designs. And I will look at that information and try to withhold my predisposition towards doubt as I personally think that solar is a much better way to go until we crack the fusion problem. I think that solar should always play a part, even if it is as simple as facing your house to true south with windows and building a trombe wall, eutectic salt chambers, etc. So much less energy would be spent if we focused on a little bit of good engineering in the housing market and conservation.

It wouldn't affect the earth's rotation that much if it hit head-on. The asteroid looked to have much less than a thousandth the mass of the earth.

I have some minor problems with this visualization. It didn't seem like much if any of the debris reached escape velocity, but it should have given the size of the impact. The oceans wouldn't boil that quickly because the air isn't that efficient at conducting thermal energy. And the shockwave would have passed through the ground much more efficiently than through the air because it's denser (which is why tin cans on a string make a phone of sorts), so you'd be shaken to bits before that silly firecloud (which should really have been a superhot blast of compressed air) ever hit.

Compressed air duster also removes porn, viruses and dodgy msn contacts.

Magnetic super-erasing feather duster can be waved gently in front of your hard drive to fix most windows problems.

I agree that it is a fake, but remember that many (most?) thermographic imagers provide options for white hot, black hot and colour interpretations. I'd so love to get one of these cameras to play around with but they're super expensive and if higher resolution, are tightly controlled if not used for military purposes.


Yes, there is white hot and black hot options, however we know the FLIR in this is white hot because of two reasons:

1. In the upper right corner of the video is the word WHITE, indicating it is on the white hot.

2. The person in the video is showing as white. Since humans keep a sustained body temperature of 98.6F, it's either compressed air or a zombie breaking hot wind.

>> ^volumptuous:
Apparently this video is over a year old. I was wondering why his fart and fingers would be black (the passerby's fingers too).
But it seems that he's holding an aerosol can of compressed air or something, with his left hand. I don't think a fart-cloud would be that perfect going through underwear and then thick-denim jeans.
Funny fake.


More evidence this is faked with aerosol can of compressed air:

We are looking at a black and white FLIR (Forward Looking InfraRed) camera. White parts indicate heat, where black indicates cold. I don't know about anyone else, but my farts are NEVER cold.

edit: Just noticed spitfiredragon also came to the same conclusion. Didn't mean to steal the thunder.

Doesn't look like it went supersonic, almost, but not quite.

Don't know about you, but my indication for whether something's gone over the sound barrier usually is the sound it makes


hahaha! Well this is one of the rare cases where you can see it as well as the vapor is an indication that the compressed air hasn't pushed its way off the tail of the plane causing the boom your talking about

Fluidized sand is just normal sand with compressed) air being pumped in. It acts like a liquid until the air is shut off, then it acts like normal sand again.

But in this experiment they shut off the air before dropping the ball. The sand was just very loosely stacked. Have a read of the article published in Nature in Dec 2004, it's only one page so I've put it up: here
