Picture a multistory building with a glass tube in it, more than 5ft across. At the bottom of the tube is a grill. Underneath the grill is the biggest freaking fan you have ever seen - totally filling the tube. This is a vertical wind tunnel that can let you fly like a bird.
When the fan is turned on, the wind is so strong that it literally BLOWS YOU UP INTO THE AIR. You wear a special suit - that is loose and baggy to catch the wind, helmets, etc. Sneakers are fine - but no loose shoes (flip flops).
You can use it to learn how to skydive - or just for the shear FUN of doing it. If you do it often enough you can learn how to do tricks, but the first time you try it you will need an instructor to show you how to simply stay floating. They will also show you some
It is very safe. You can't fall very far even if the power is cut (the fans slow down gradually, bringing you down gently). They say you don't have any trouble breathing in the wind, but I think they are underestimating that issue. If you have allergies (runny nose), asthma, or similar issues you may have some issues breathing. I would at the very least take any appropriate medication. Basically, stick your head out of a car window at 55 MPH If you can breathe fine while doing that, then you won't have problems. But it is at the very least very annoying. Do NOT do it if you are sick.
The cost for a simple try was reasonable - but they "get you with add-ons". Anything besides the most basic experience costs more. Want a 'high' flight? Costs more. Want a video? Costs more. Want to rent a nicer helmet - that makes it easier to breathe? Costs more. The training for your first flight also makes it more expensive than later ones. Also, location and time will change the price - weekend premium. They offer group pricing, which helps somewhat, as does bulk purchasing for one person. If you are a teenager and fall in love with it, you could get a job doing it.
It is not that hard to do the basics, but it takes a while to learn to do the harder stuff. It doesn't take any muscle - young children can do it.
While this is cheap, easy to learn and easy to do, it is not located near everyone.
It trends young and male, but there are women doing it. Kids as young as 3 can do it. There is no upper age limit. They do have a weight limit. But you can do it even if you are a paraplegic. They do offer parties, if you have the money.
I did it twice, once in Vegas
and again with my niece and nephew while in Austin Texas at a chain iFlyworld
