wait what was the trick mc do or am i just dumb

It's an old trick I also used to do in middle school lol
Basically he folds one of his thumb while covering with the other hand and aligning the other thumb , so when he moves the hand it seems like he detaches his thumb.

Hope you understood my explanation! >.<

explained it perfectly! the trick is that it looks as if the mc detached his own thumb!

thx lol

I first saw that thumb disappearing trick and kept tryna do it when I was like 4 lol from the Barbie Fairy Secret movie that Ken did-
