Me and my friend found this out a couple of days ago. All you need is an air compressor, a golf ball, and a nozzle that lets you spray air when you press it. You'll find out what I mean in the next step.

This is my first instructable so it is not perfect.

Step 1: Materials

Here is a list of stuff you'll need.

1. An air compresser
2. A golf ball
3. A nozzle

Step 2: Hold It

Hold the golfball about 6 inches above the nozzle. Make sure the nozzle is pointing upward. Be sure to have your hand on the trigger of the nozzle.

Step 3: Blow It!!

Now shoot the air out of the nozzel and let go of the golfball a few seconds later. If you have a weak air compressor hold the ball closer to the nozzle. Now you can turn it to a 40 degree angle and it will not drop. You can use a practice ball and it will go much higher but you can't really turn it sideways so....
This is like the ping-pong ball and the hairdryer. But you need an air compressor for the golf ball because it has more mass. It's the Bernoulli principle (for the people who don't know). The ball stays in the air stream because it is in a lower pressure area. The higher pressure on the outside keep the ball in the air stream.
I feel bournoullis principle should be used to more effect, think how easy getting a lift would be if you didn't have to stop at floors for other people...
That's an odd concept, explain more about it.
Umm Elevators that blast masses of air up hollow tubes, there's an up tube and a down tube, the down tube has just enough air to slow descent but not falling quickly... People simply jump in their respective tube and grab handles to stop at their floor and open the door, since it would actually not take that much serious mechanicals it wouldn't be overly costly, the main expense being a fan powerful enough to do the job, none of the usual elevator equipment would be necessary and the original door would only need to be fitted with rubber seals and buttons for the insides of the tubes... Not sure about efficiency but coolness, defninitely, though in exceptionally busy buildings this concept could prove cost effective and even efficient...
Now getting off at the right time would be a different story. Miss a floor and you're pretty much dead.
Not really, the idea would be that it would go up at a speed reasonable enough to catch your floor and the top floor would have a big mesh ceiling and handles to make your way to the door...
There would be many variable to take into consideration, like mass of a person, and their surface area.
Yeah but it would still be cool
Kind of like the tubes in Futurama.
Yeah...
you seem to be forgetting that many people use elevators for such things as boxes, bag's children in buggy's/stroller. it would be cool for the people who don't need to use it for any of this but other than that completely useless.
it's a if the world was cooler idea, not a perfect point, however an elevator powered by this system could work in principle, it would simply be tightly fitted in its shaft and be a moving platform...
I would love to play in an elevator like this. Very similar to those wind-tunnel things that simulate weightless-ness (or a free-fall sky dive, or something similar), but I reckon it would need a huge fan.
yep, I reckon on big **** off fan is in order...<br/><br/>*delivery guy, need someone to sign for a big **** off fan<br/>*Woah that's on big **** off fan<br/>*wel ya going to sign so I can **** away off, it's my lunch.<br/><br/>Note that was overuse to make point of fan's big **** offness...<br/>
Hmm, maybe thats a little too big? I was thinking golly-darn big, not ****-off big...
hehe...
I can do this with a ping pong ball by blowing it upwards.
By the way, quit spamming.
What are you talking about spamming, I got started on a related topic, then made a forum topic to cover it, people still reply to this though.
Or did you mean the author?
Yes, I mean the author. Check his comments.
Oh right, sorry launched into one, then realised, sometimes you get the odd person that calls it spamming to have a conversation on an 'ible... Even though all benefit...
Cool! My text is squeezed because of useless comments(no offence)!
The conversation was actually topical so meh...
let us extend this
Even more?!?!
yes
Even more!!!
the prophecy has been fufilled i posted again
you guys never finished it
Even more!!!
lol how many females in an office wear skirts??? heheheh
Not enough...
I like the way you think, haha!
Chec out the parachute simulator ideas, it's not a completely unbelievable idea...
on the whole elevator thing, you could have a pad u stand on before entering the tube which adjust the fan to accompany your details, and then choose your floor. enter the tube, your balanced out and then you proceed down or up.
