Balancing the Books
Last Tuesday, we came up with the idea of guessing how many books can be placed at the edge 1/10 of the table before they topple down. We realize it takes a little bit more than half the books to be on the table before the pile goes down.
First we estimate that it takes 6 books before toppling down.We carry out an experiment. It actually took 5 books, just as the hint suggested. So it can't be above 5 books to be placed on the edge 1/10 of the table.
My friend and I found this an interesting puzzle
We used exercise books. Maybe you can try using a thicker book to see whether it works or not. Have fun !
