Slick back tutorial
(files.catbox.moe)
Videos of anything that clearly has no explanation other than no good black magic voodoo fuckery
In essence the tutorial is right but the trick is in the transition but that takes practice.
It's but like street magic levitation, although that is easier. After my brother and I saw it explained by the Masked Magician, we both gave it a go and nailed it first time.
