I would like to just add some stuff in this thread.
I learnt this trick at the start of the year and was also put of a bit by the price. So many effects cost a lot which end up not being as practical or useful.

Isolated is absolutely worth every penny and the refill pack gives you plenty to re perform the effect more than once.
In my opinion this is such a hard hitting effect with a souvenir that will be talked about for more than just the rest of the evening.
I also love the flexibility of the performance with this. You can adapt and make it your own presentation as you only need one move in order to complete this and even the move is not really a move.

100 percent one of the greatest tricks I have seen sofar.

Does any one know the make of the speed cubes used please?

I messaged Kieran a while back and he replied back with shengchan but I think he meant shengshou. Which model it is I’m not 100% sure, but it looks almost identical to the shengshou legend cube. I say almost identical because there’s always a little room for error when it comes to internet photos.

I ended buying one, I’ll write back when it gets here to confirm, but if you’re thinking about buying one make sure to get the black cube with shiny stickers. Hope that helps somewhat. 🙂

So the speed cubes used are Shengshou Legend Cubes, you want the black with shiny stickers version. I bought one as a test and it matched them perfectly. I then bought 3 more cubes for $9 for all 3 of them. I used davidcube.com , but I’m not sure how much they have in stock 🤷🏻‍♂️

I have trepidation doing a "vanish" of the cube,other than doing it the same way Kieron does what other options do people use?
Could it be done as simple as putting it in a paper bag into RD360 doing neccasary load? Bring out "solved" cube do the "caught me out" gag then bring out jar? Obviously there has been no time for you to feasibly put cube in a the jar from specatators POV but also seems a lack of "magic" happening.

That is how the RD360 self working version is done.

Does anyone know where to get rubiks cube made from paper that look real? Rune Carlsen uses one in his act to "vanish" the cube for Isolated.It looks very realistic.
