things you can't do

[MackemX]

I know you can't touch you elbow with the same hand on that arm. You also can't tickle yourself (maybe a pervert could) but is there anything else people can't do?

:edit:, answer truthfully 'yes' when asked the question 'are you asleep?'

:P, OK clever . I suppose someone with quite long fingernails also could



actually have you seen the video of that kid with the double broken arm? I just came across it earlier today and you just can't tell if it's real or not

piss and whack off at the same time

I can. My feet are really sensitive.

answer truthfully 'yes' when asked the question 'are you asleep?'

I've been told I talk in my sleep, as well as answer questions.

yes,its called lucid dreaming.knowing youre dreaming that is.

Can you "go f&*k yourself"?

What do you mean you can't tickle yourself? Why would that be? I don't see why its any different than if someone else did it.

I suppose there are some people who could do it but if you squeeze an egg on its two outermost points (top and bottom of oval) its supposed to withstand an extreme amount of pressure such that no one could break it...at least that's what my sciene teacher in grade school told me. Works the same way if you squeeze it on its sides but with your hand completely cupped around it.

Another thing you can't do is open an airplane door while the cabin is pressurized.

[mastersmurfie]

you also can't stick your elbow in your ear or your eye(either one...try it... )

Another thing you can't do is open an airplane door while the cabin is pressurized.

It's not impossible to open cabin doors in flight, just very difficult (perhaps depending on the type of airplane). If you're up at max cabin dif altitude (say, 35,000 feet), the cabin dif pressure will be around 8 psi. The A320 door opens upwards and inwards first, and if you were tremendously strong, you might be able to move it a bit. But open it all the way, I doubt it.

At lower altitudes, you have lower cabin dif pressure, so things get easier. I wouldn't want to guess, but at some point, maybe, if you're strong, you should be able to get the door open.


Having opened the door, you're going to have to fight the wind, because all the doors on the A320 open forward. So you might have a tough time squeezing out, if that's what you're thinking of doing.

Commercial aircraft dump cabin pressure when they land, if not before. Therefore, evacuation is not a concern.

Very briefly, the evacuation system on doors (A320) works as follows (you'll be sorry you asked):

The door is closed. The door has a flat bar called a girt bar, which sits at the bottom of the door, and is attached to the slide firing mechanism. When the door is armed, the girt bar is pushed into two fittings mounted on the floor. Thus, the slide firing mechanism is now connected to the aircraft (as opposed to the door).

With the door armed, the inner handle is pulled up (opened). The door begins to lift out of the door frame. The girt bar is held in place at the floor. The girt bar pulls on a cable, which is connected to the door slide inflation bottle. The bottle fires, and *POOF* the slide appears through a cloud of talcum powder.

Simultaneously, as the door is rising in the frame, a bar on the door strikes a firing lever on the door assist bottle, which is mounted on the support arm. The firing lever releases a small nitrogen charge inside the bottle, which pushes the door open (whether someone is hanging on to it or not).
airplane doors can be opened while cabin is pressurized .. emergency exits can not ....

but -- a recently mandated safety interlock somewhat prevents this (they still can be opened about 3" though - BUT not on all airlines or aircraft has this been done .... boeing had a recall on this issue ....


remember D.B. Cooper with $200,000 in his mitts parachuted out of the rear exit of a Boeing 727 flying over Washington state as one example ... but that was only at 7000ft or this one also http://news.bbc.co.uk/2/hi/asia-pacific/763341.stm

it would be pretty hard. a 737 or 757 style door, for example, has to be pulled inward before you can swing it out and open. this would require overcoming lots of pounds of pressure.

On a B743 or B744 it is IMPOSSIBLE to open the doors, at any altitude as there is an automatic lock security that is activated when the wheels of the main gear leave the ground. The doors are unlocked automatically the same way when one wheel of the main gear touches the ground on landing.

The door on a DC8 is not a plug door. It can be opened with a pressurized aircraft. It will get real exciting real fast at anything above 14000 feet.

Doors on most commercial airliners are plug doors. That means the door must enter the aircraft before it can be closed. Their are a variety of ways to achieve this. The B767, for example, has the door physically mounted inside the airframe. Other aircraft, B727 or B747, have gates at the upper and lower ends of the door. These extend after the door enters the airframe and close the gap to seal the door.
A310, 330 cabin, L1011 cargo C1 C2 C3-not C1A, B757 cargo c1 c2 not c3 bulk are all NON plug doors ...

I suspect that A300 does not have a plug door. 1) I can't find it in the description and operation. 2)it has a "residual pressure" system installed in the door to warn of a pressurized cabin. You are not supposed to open the door with the light on. 3) I've heard of several crew members getting hurt when the door is opened and the aircraft still slightly pressurized.

a (707-320) overwing hatches can be opened in flight, to vent smoke, though the flight engineer changes the pressure before this procedure is done, and the pilots sliding window is also opened. There is a way to do this at 15,000ft on a 747 also (old models) ..

Closing doors sometimes requires a special technique, especially if the pilot has to leave his seat to get to the door. The crew of a Beech 99 that was deadheading back to base got an open-door annunciator, and the captain went aft to close the door. Whatever his plan, it didn't work, and he found himself outside the airplane, hanging onto the now fully open door. Unable to move, the captain hung precariously for 10 long minutes while the first officer headed for the nearest airport, fearing that he was now the pilot in command and sole occupant of the 99. The landing was uneventful, and the captain certainly gained a new respect for the line in the check list that reads "doors and windows – secure." That's good advice, and we should have an open-door policy thought out in advance.

here is a pic of one landing after the cargo door popped open in midflight

@BJ_M, did you just write that post yourself and only quote the quotes? If you did then you know your stuff about planes

@adam, you will get people who can tickle themselves but I'm talking the vast majority here. I don't the the techinal stuff like BJ_M does but basically when you tickle yourself your brain doesn't go into panic stations like it does if it's someone else doing it

another is that most people can't lick their elbows

[MeDiCo_BrUjO]

@Adam, I have actually tried that thing with the egg and it really works, you just have to know how to grab it. If you apply enough pressure, your hands will hurt like hell and the egg will be intact.

[Treebeard]

I have tried the egg thing also, its pretty cool. but if you squeeze it with uneven pressure you get a mess.

[MackemX]

will it be the same for my head in a vice?

sometimes I do hear people say to others 'Oh, go put your head in a vice!'

[BJ_M]

try it and get back to us .....

isnt that the truth
