magnet

What ok said... but expanding slightly more, magnets are not useful to change the parentage of something. Magnets have something follow its parent, or stop moving with parent. As soon as you want the parent to change (in your case, stop moving with head and start moving with hand), you need to use something like different copies and a swapset (as oi said). Eg you can carry then put a cup on a table and leave it there, but if you want to pick it up with the other hand you need a different cup and a swapset to flip between them so it looks the same, but it's actually a different cup.

I wouldn't recommend magnets for this sort of thing. Instead, I would put the toothpick in a trigger swapset where its default position is on the mouth, and a trigger swaps it to appear in the hand. That will be much more reliable, I think.
