How is it done

[ctsibos]

hi all,

I have seen a really cool trick with bubbles of air been performed underwater. the diver blows one "ring" towards the surface and then a second one. Somehow the second ring catches up with the first and goes through it. I dont know if you guys have ever seen that but does anyone know how it is done i.e. is there a specific way one should blow to get the desired effect or is it just liquid physics that explains it

thx

My instructor in OW showed us this in the pool. I've also seen divers much better than me do it during a safety stop. I can't do it. Maybe I'm still just so focused on the vital skills. Maybe I will have "arrived" when I can play tick-tac-toe on a slate or blow those bubbles during my safety stops.

Hmmm...I've blown bubble rings before but never the "one through the other" trick...I'll give it a shot in the pool tonight.....

At the risk of being dis-barred from the "cool kids club" I will give you a little hint on how it's done.

Remember that bigger bubbles rise faster that little ones... right?

 

[Joe-Diver]

Yeah, that's what I was thinking....

thanks for kind replies, what im amazed at is the physics of it. even if the larger ring rises faster still doesnt explain why it doesnt simply crash on the slower moving one but kinda gets swallowed by it

Or fart in the wet suit roll over so it follow up to the chest then raise an arm and used the other hand to release the fart from your sleave wrist..made rings like this too
