How does one hitch a lift on a flying saucer?

" They " would choose you...you don't choose them.  You don't go out and hold up a sign along the road hitching a ride.  It's not like putting an ad in the paper stating that you're seeking to get a ride across country and will chip in for gas.  ' They ' would choose you...not you choose them.

gravity and air resistance.

1.  Hurl it spinning into space.  The vehicle will spin around its center of gravity, and its center of gravity will travel in a straight line.\n\n2.  Balance it on a see-saw three ways: upright, on its side, and on one end.  Each balance will define a middle plane that cuts through the vehicle.  The intersection of the three planes is the center of gravity.

The forces are gravity down  and air drag up.\nIf you want your egg to land softly, one way is to increase its coefficient of drag -- give it a parachute.

You don't. You need a scam.\n\nThere is the force of gravity.\nYou need an equal and opposite force to counter it.\n\nSeeing people protend to levitate is fun to imagine\njust like Superman flying through the air, being invincible, living forever and shooting beams of light out of his eyes. But, it is just a fun fantasy.

I see flying saucers there all the time.

High voltage electrogravitic levitating aluminumn foil triangle...aka..."Lifter"\n\nEven if you dont do this you gotta see the video clips.  A balsa wood frame and aluminum foil body, hooked to >20k voltage supply makes it levitate.  This has been replicated over 100 times by all kinds of people.

You can do it with a laser a small circular obstacle (1cm diametre) and some lens. You built a telescope like picture to have 2cm diameter beam  you put the obstacle in front and you regard at 20 cm from the target

The other alternative is to flag down the next passing UFO ..it seems the little buggers are more than willing to give anyone a free ride...you just wont be able to remeber it..

Lots of variables here. Do you want one that will move with directional intent, or one that just floats?\n\nThe simplest method for making a "hovering" vehicle would be to take the vacuum engine, mount it onto a curved shield, with the curvature facing down. Make sure your shield is a very light material, balsa wood works, i suppose.\n\nIf you know where the vacuum's intake and output valves are, then it's easy. make sure you make a hole for the output, and secure the engine to the top of the shield. Turn on the engine, and watch the contraption float around aimlessly. It's basically how a air hockey table works, except in reverse.\n\nEDIT: one important detail. Are you trying to make a hover car strong enough to hold your weight? Because that would need one hell of an engine.

If they have a fairly long distance to travel there is a group of volunteer pilots who will help with this. Check online for  "Angel Flight" There are certain restrictions that apply and flights may be dependent on weather, pilot availability etc.

Try this...Take a square piece of paper and fold it into a triangle.  Now fold a series 1/4 folds (3 or 4) on the wide end.. then insert one end into the other (if it doesn't stay then use a small piece of tape to hold together)  What you will have is a cylinder type of craft.. to launch it hold it by the tail (the tip of the triangle) with your middle finger on the inside and all others on the outside... The position should be that the most paper should be facing down\n\nNow just flick you wrist and let go... if you did it correct you will have a futuristic paper air plane that will fly further than most conventional ones..

It won't be very easy.  Almost impossible.  You will find that with an airtower and fatsack that it will be so much easier to get the height you need to make a full revolution.  What is a ski supra, by the way.

Without the math, here goes:\n\nFirst problem is the weight and dimensions of the ball - you need a heavy ball for the gravity portion of your power extraction, however you'll need a light ball (less dense than water) to achieve any power from the buoyancy. That means that if you are going to have any significant buoyancy, you will not have enough weight in the ball to refill the canister and if you have a heavy enough ball to refill the canister, it will not float. This appears to be an unsolvable condition without the addition of another external energy source.\n\nAnd if you could overcome these concerns - how would you get the ball back at the bottom of the canister once you move it over and let it fall?\n\nBe that as it may, using buoyancy and gravity (opposite forces) to produce energy is an interesting idea.

Use the very tip of the point to open the shaft and use good light. If your blind like me you won't ruin the flight.

A guy that could fix the lift from inside the lift :)

Lift of WHAT?   Crane, Ballon, Brassier, Airplane wing....???\nGive us a CLUE
