Tricks like Skutz Triangle and Magic Trick?

I just learned these two tricks tonight. 
Do you all know any other tricks like these? Tricks where people think your string is a crazy tangled mess and then POW … your string is fine.

Mryoyothrower has a nice one from wrist mount on his youtube channel but i forget what the name of the trick was

Thanks for the rec.  I do not think I have found the one you are talking about.  But I found another pretty good one on his channel.
