easy go to walmart buy hamster water bottle the kind with little ball in end of tube and fill with favorite lure or scent tape string to side hang about 5 feet over mock scrape small holds about 8 0z lure last about 1 month.or just put apple juice in it.
You have a picture of one ?
Does the string go into the bottle or just to hang it from? How does it drip?
I think the string is to hold it up.
I also think the little ball is not water tight
and the scent will drip out slowly.
Any way a good idea
