Back in 1992 inventor Guido Lap came up with the idea of interchangeable strings. Ten years later Brainstring Original was introduced and almost immediately became a worldwide bestseller.
Now you can play with this great new version of the Brainstring Houdini.
Any string is interchangeable with another, so there are many possibilities for play. All imaginable combinations can be made.
Move each button one-by-one by simply gripping and lifting the button, pulling it and the attached elastic into its new position.
