DIY: How to make a small jar with a cap, from an old plastic bottle

Things you need:

2 empty plastic bottles

A knife and a stove to cut the plastic bottle finely

Glue gun

 First, heat the knife on the stove and cut the plastic bottle just below the cap, as you can see in picture. 

Now, take glue gun and fix a bottle cap along the cut edges of the bottle.

Take the second cap and place it normally as on a bottle. Now you're done making :) also you can paint it.
