Is there a way to experience Zero mavity without......

[The Dread Pirate]

Dig to the centre of the earth!

Well if you are falling at the same speed as mavity and don't feel air resistance, that is a pretty good simulation of mavity. Far better than skydiving or the wind tunnels which simulate sky diving, which do not let you accelerate at 9.8 m/s^2. If you jump, this is a pretty good simulation, as air resistance will not be too high. Obviously, it won't last too long... A trampoline could help a little bit, but of course, as you jump higher, air resistance will take more and more effect...

Buy a trampoline.

If you are in a black box, ie no windows, and the box (with you in it) is in freefall, can you tell the difference between freefall and zero-g?

Yes.


Usually around the time you smack into the ground

 

[gillywibble]

jump from a stupidly high building.

The leaning Tower of Pisa is generally regarded as being the most appropriate, if you've got the balls that is

 

[Tefal]

Some sort of spacehopper style impact Cushion?

Diamagnetism

It has been used to levitate a frog so if you just upscaled it, it may work?

You could always try this for the old Falling out of a airplane,

its not 0 mavity but its a skydiving wind tunnel, basicly you sit ontop of a huge fan and "float"

not cheap though

Outch, that is expensive! ~£40 for 2 minutes

Does look fun though , given real skydiving costs around £350 IIRC, but atleast you can do a 10,000ft jump

It takes a lot of power. Hence the expense.

Real skydiving can be much cheaper than £350, especially if you start with a solo course!

Not quite like zero mavity, but as close as I think I'm going to get... sometimes the plan rides are a bit "zero g"!

Isnt there a split second in skydiving where the downforce matches the airs upforce thus giving you a moment of weightlessness?

 

[Wings]

In skydiving your drag equals your weight and therefore you fall at a constant (terminal) velocity of ~120mph... but this isn't weightlessness, and doesn't really feel the same (I would think, having never been in true zero G), as you are constantly in 120mph winds (imagine sticking your head out of a car window on the motorway, but twice as fast and over your whole body), and as such isn't as 'calm' as zero G looks.

You can, of course, flail around to your hearts content, and you have no part of your body on the floor... so in that sense I suppose it is a little like zero G

EDIT: Jumping from a balloon, though, means that you start from a velocity of 0 and don't notice the wind for a few seconds, so that may be a closer representation. You do get the "drop" feeling in your stomach though.

Downforce is not what you're thinking it is.
That's the act of aerodynamics to create downward pressure.

 

[DJMK4]

Ah sorry my mistake

As far as rides go Mission Space at Epcot definitely felt weightless when you simulate coming out of the earths atmosphere into space. But it's just the transition of going from quite strong gforce pushing you down to none at all. Bleedin' good ride though!
