It can be made up on the spot (if you bring scissors with) but the angles aren't as good as the ones in the video (the camera footage wasn't as clear as even phones today are so it didn't catch the flashes you would make at those angles... also the white bursts in the trick demo were added to cover all the flashing made while performing the trick).

The explanation is concise, the gimmick is simple to made, and the trick is flexible (again, keeping in mind that the angles are extremely weak and should mainly be witness from above).

the trick itself looks impressive the gimmick is ver easy to make you just cut it out that's it and do what it says to do but the angle are not great.but everything else is great .
