Touching the mercury !!!!!!!! Bare handed !!!!!!😱😱😱😱👁👄👁

Nice video

Explanation is excellent but this might not be practical as mercury is toxic... So for students water experiment is best...

Mercury should fill up the test tube COMPLETELY before sealing it with thumb. Please change the animation accordingly.

👌

Thank you
