I'm still continuing my fascination with what can be done with plastic bottles and lately I have been experimenting with making a wall hook out of the handle of an Odwalla bottle.
Step 1: things you need
A plastic bottle with an included handle, like an Odwalla bottle or vinegar bottle.
Small soda bottle cap
drill for hanging
drill bit for a pilot hole
three longish screws
polymer clay (or something else to fill the inside of it for strength)
some commenters suggested using concrete instead - which is inexpensive and an interesting alternative
vapour mask and hot knife (or you can use scissors though I find the hot knife easier to control)
largish glass or plastic container
(optional) plastic paint
