Human: How do you make a homemade hammer? Assistant: 
You can make a homemade hammer by using an old wine bottle. First, cut the top off of the bottle and remove the label. Next, use a hacksaw to cut the bottle into two pieces that are about 1/2 inch thick. Then, use a drill to make holes in each piece for the handle. Finally, attach the handle to the two pieces with screws or glue.
