the metal wand is the cannula. next time i think we will try a plastic catheter rather than a metal cannula. the cannula wasn't long enough to reach the fundus (the top) of the uterus. after habibi put it through the os (the opening of the cervix), i could barely feel it.
and it needs to be able reach all the way inside the uterus.
you can also see a tiny bit of menstrual blood (mixed with water) in the jar...
the tube coming out of the jar is cut because we cut it after we were done with our experiment. during the process that tube is not cut, it is connected to the syringe...
