How to untie a knot in a plastic bag
So, the cashier at the store tied and tightened a knot in a plastic bag for you, or you already bought a packaged product in such a bag. What did you do before? They tore the package apart because they didn’t feel like untieing the knot with their teeth.
And now I’ll show you a simple way to untie such a knot.
To fully master this method of untying packet nodes, you will not need anything other than a little and short practice. So, in order to untie a tight knot on a plastic bag, you need to grab the very edge of the bag above the tied knot with your fingers.
Holding the ponytail with your fingers, we begin to carefully twist it in a spiral so that we get a sort of braid or tube. With each movement, the “pigtail” will become thinner and stiffer.
As soon as the tube reaches a sufficient level of hardness and rigidity, you must, without letting go of the “pigtail” with the fingers of one hand, grasp the loosened knot with the fingers of the other hand and help them push the pigtail through this knot. Nothing complicated, no magic, just sleight of hand! Congratulations, the bag is untied and there is no need to tear anything.
