Should you have any unused or come across any discarded plastic bottles don’t throw them away as they are useful. And one of the usefulness is they can be used to form wood-joints as demonstrated below in the video.
This wooden joining technique can form strong joins. They can be bent without breaking. Perhaps it there is a need to dismantle the joint, a simple pen knife will do.
After fitting the items together, the joint can be formed by using a hot gun.
And the test of strength.
