I'm relatively new to all of this, only having started reading about it in July.
However, I'd just like to share this opener with everyone here, since i couldn't find it mentioned anywhere on the forum.

Being a resident of london, i take public transport a lot to get from place to place. What i've found strange is the fact that you're surrounded by loads of people, yet noone really talks to each other, yet everyone is still aware of who is around them. This opener takes advantage of that fact, and is just meant to be used a a neat way of easily opening sets on trains.

It is best done with a wing, and as the name implies, it involves solving a Rubik's Cube whilst on the train, preferably sitting near some HBs

Learning how to solve a Rubik's cube only takes about 10-30 minutes, and can be learnt off Youtube.

After learning, it only takes about 3 minutes to do max, but initially, start off by just solving the cube once or twice, taking your time.
Then go into something like this:

Huaii: (conversational tone to wing, but able to be overheard) Dude, do you think i could solve it by the time we get to the next station?

Wing: Go for it man, i don't think you'll do it.. but you can certainly try..

Huaii: (To set) What about you guys? do you think i'll be able to do it?

HBs: *Shrugs shoulders, replies with maybe, yeah! etc.*

Huaii: Okay, we'll give it a go.. *solves it before next station*

HBs: Wow, that was pretty cool!

Then run into routines from there on. I've even managed to show an HB how to solve it over the course of a long train journey, and #Closed at the end of it

Seeing someone solve a Rubik's cube is impressive.. however, it only takes under 3 minutes to do, and combined with the time distortion that is encountered when on the underground, it looks really quite amazing.

It takes some practice, but it's always allowed me to open sets with ease.
