Oxygen bar

I'm tempted to try one of those. As anyone have experience with them?

equipment seem realtivily cheap...

I have a couple medical oxygen concentrators but I use them for mad science and not breathing. If you want to play with oxygen you might want to look into a used oxygen concentrator. If you look hard enough you can probably score one of the big older ones for free.

WHY do you want to try that?

There's no danger in it unless you have certain pulmonary problems, but there's no, zero, zip, nada benefit to it either.

If you want a bit of a high, just hyperventilate. That's free.

Intriguing idea, but it seems kind of placeboish unless you actually have a medical condition, in which case, go to the ER or do O2 therapy at home if you have the equipment.

Also, O2 bars seem to just have cannulas from what little I've seen. Masks are what trips my trigger.
