the water in test tube b was supposed to be boiled in order to remove the oxygen from the water
Complete waste of time because he is asleep the entire video
Not helpful whatsoever

his voice is quite boring and it makes the video lack entertainment.

Hi. Great Video. I am putting together Chemistry videos for E-Learning Jamaica Project. Would appreciate it if you provide me with an email address where I can send you a letter requesting permission to use your videos in the tutorials. Thank you
my final test .. T.A
So if the oil was not present would then the nails rust in test tube B? If so would this be a slower reaction that test tube A?
The experiment seems to be lacking a control. Other than that, good video.
really good! I don find anything wrong w the voice. it's clear, n easy to understand ((: thanks for all e videos!
ps at 1:57 "Nails in test tube B donot rust" ... really? donot? Do not or Don't. wow..
The voice on this is..well..terrible. Half robotic even
