A video clip that caught my attention
Title of video: World's roundest object
content:It is about how the worlds roundest object defines the kilogram.
What I learnt from this video:
1) Kilogram used to be called grave.
2) The creator of grave was Lavoisier
3)The kilogram is the only base unit with a prefix in its name
