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.
To make a simple microscope out of a plastic bottle, you will need to cut off the bottom of the bottle and place a small drop of water on the flat surface created. Then, take a clear piece of plastic or glass and place it over the water droplet to magnify the image. Lastly, hold the bottle up to a light source to illuminate the object you want to view.
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 :)

To create a drip irrigation system with a plastic bottle, first poke holes in the bottle using a pin or small nail. Fill the bottle with water and bury it next to the plant you want to water. The water will slowly drip out of the holes, providing a steady water supply to the plant's roots.
