Here is what you need:
plaster bandages, wire, paper balls (1 large & 2 smaller ones), scissors, sharpie marker
To hold it there you can let a clothespeg rest on the container.
Make some big (20cm or 7,5") and some smaller ones (10cm or 4")
add the smaller paper balls on the ends.
rub over it so that the holes fill itself with plaster.
Happy Halloween! :)
