Câu hỏi:
If you have two quarters on a table touching each other, how can you move one of the quarters without touching it? You are only allowed to touch one quarter but not move it. You cant touch the quarter that you move. You want to get at least enough room between the two quarters to insert another coin between the two quarters.
Đáp án:
Hold down one of the quarters very firmly. Take another coin and hit it against the quarter you are holding down. Tap hard enough to move the quarter next to it aside.
