The House point hourglasses are located in the Entrance Hall. They record the number of house points that have been awarded or deducted. There are four giant hourglasses; one for each of the Hogwarts Houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. When points are earned some gems (depending on house colors) fall from the upper bulb into the lower. When points have been deducted, they do the opposite, retreating into the upper bulb.
