Use this to suck up boogers, wash out your nose, or to clean your ears with peroxide, provided you used a safe material. I do not recommend using this, as it may use too much pressure and damage your eardrum among other things such as being a breeding ground for bacteria and unknown toxins from the filament.
Update: I went to the doctor and they used the elephant ear washing system on me. if that thing is safe for your eardrums, there's no reason this shouldn't be. You just don't know what they put in that TPU, though.
