I would try heating it with a heat gun while pumping air into it, at low pressure. If you don't want to deal with hooking up a pump which would require gluing a bicycle valve through a hole in the cap, then you could achieve pressure by putting a small amount of baking soda and vinegar. Small amount.
you get a plastic bottle
Here is one idea: using scissors, cut the bottom off the bottle. Starting anywhere at the bottom, cut in a spiral from the bottom to the top.
Empty pop bottles are made of glass. Some are made of plastic. Ther is usually a recycling code on the bottomof the bottle or near the bottom that indicates what kind of plastic was used to make the bottle.
The easiest way to make a drip irrigation system from an old plastic bottle would be to punch a hole in the bottom of the bottle and connecting the bottle to a section of drip tape using a piece of spaghetti tube. Then elevate the bottle above ground level so that gravity will move the water to the drip tape and to your plants.
depends what you want to make
Plastics make up the majority of bottle caps. They might also be created from metal. Based on its intended use and the type of bottle or container, the material used to make bottle caps is selected.
no because the heat would melt the bottle :)
