Hmmm .... I used to use the bat aaaaages ago.
From what I remember, it's quite powerful - it would move a coin through a standard pub table - about 1" thick.
You can clip this to your belt to perform the linking/spinning rings and it'll stay there all day, or you can strap it to your leg to move an object on a table etc.
You'll have to make your own strapping - but it should stay there for quite a while - you just need to adapt it to fit nice and snug.
I forgot about this lil' beauty - I think I'm gonna have to dig it outta my drawers for tonight's visit to the pub
