i saw this on youtube when i search for physics experiment for the exhibition on the coming saturday..
itis a simple physics experiment on centre of gravity..
i decided to try it out..and i did it..
you can try it too..
First, i need a pencil
pierce the pencil with compass..
and it become like this..
now i try to put it at the edge of the table..
my hand still there..

and i try to put it on my finger..
and i want to make another one..
i replace the compass with a nail cutter..
please note that it is not necessary to use the compass.. we can use a knife too..
