If you accidentally drop the plastic bottle and get stuck in the trap, don’t worry, try using the following method.

Then, one end of the wire is tipped, bent 135 degrees from the tip’s diameter equivalent to the diameter of the nozzle, and carefully inserted into the return bend to turn the wire from the nozzle, so that when the plastic bottle is touched, Kex is used again.
