A Stainless Steel slide has many small holes in the surface. Air is blown through the holes, like in Air Hockey games.
The slide becomes so slippery that the angle and maximum height can be reduced, so it is safer.
A side benefit is that the slide can be "turned off" when not supervised/required.
Not
inspired by the "Teflon Slide", which I found after searching, but I think it builds nicely on one of the comments about sliding on air or water.
What the hell is Air Hockey?

You're planning to slide down on a rigid flat "puck" of some sort? Or push a whole bunch of air through this thing? |
|
| |
(BTW - sliding down a metal slide on wax paper a few times can really up the down speed) |
|

No puck.
I calculate for "levitation" approx 14psi is required, and after a few more calculations with 1/8 inch holes on a 1/2 inch spacing about 600,000 scfm is blown through all the holes.
This needs a fan of about 250hp.
But your behind wouldn't be touching the surface!
For economy, a smaller fan and a little more friction could be tolerated. |

You are going to need that puck I think.
I would be concerned that if the air pressure is enough to lift your weight, it might be strong enough to force its way into your bloodstream. |

Shop class 101, do not place hand over the spray nozzle of the air hose. |
|

yeah, embolisms suck. This is cool + |

Workshop air is 6 to 7 bar (about 100psi). There is a slight difference.
However, it may be advisable to put a cork in your bum-hole. |

Nice idea. By the way, good job on the research [Ling], if everyone did the math we'd have a lot fewer deleted ideas. |
