Here is a photo of the different materials we used.
We used a schlenk tube, stopcock, some protective glasses for our eyes, vaseline and an elastic rubber.
We worked in pairs so we could help each others.
1 BY 1 STEPS.
1.- We put our protective glasses on.
2.-We applied some vaseline to the stopcock being carefull that no vaseline gets in the whole ofthe stopcock.
3.- We place the stopcock again into the schlenk tube.
4.- We twist it so the stopcock isn't parallel with the schlenk tube.
5.- We make sure that the stopcock doesn't move out from the schlenk tube with the elastic rubber by following these steps:

5.- We make sure that the stopcock doesn't move out from the schlenk tube with the elastic rubber by following these steps:
- We twist the elastic rubber in two.
- We started from the bottom.
- We cross it trough the top.
- We twist it and cross it from the top again.
- We twist it again, and cross it troughthe bottom part.
6.-Then we take off the the elastic rubber and take off the stopcock and we clean the vaseline out from it.
7.- We put the materiasl again in their places.
