Tearing and destroying items
I am looking for ideas for a young gentleman who has a severe need to tear items such as his shoes (and he tears them down to the soles), his clothing (he will be naked before he is done ripping them), etc. He has a "non-destructible" string in which he is given daily and goes through quickly and then goes back to tearing other desired items. Does anyone have any other functionally equivalent replacement behavior that has been effective? thank you!
