did any one got bubbles for the second experiment ?? i tried like for 50 min but was not able to produce a single bubble ..

Yeah bubbles were produced.

i believe the volume of air that was forced out was not large enough because having a 50 cm tube and only pushing out 2 ml how could produce bubbles and above that the question said that the plunger of the syringe was too be pushed slowly how can u create a force in that circumstances ??

what were the errors and the improvement ??
