Magic Tricks

let me start off to say that i didn't even buy this effect but rather i figured it out. actually i knew this effect before i saw it on penguin magic and actually found this effect two years after i accidentally did it (not off YouTube) in fourth grade, i was learning a effect where you produce a straw from an envelope and accidentally twisted the straw. But, whatever buy this if you want or if you haven't figured it out yet because you can do exactly what it shows in the demo and it is very visual and easy to do
