Floo powder is a glittery powder used by witches and wizards to travel by the Floo Network, which connects the fireplaces of most wizarding households and buildings. With the use of Floo powder, witches and wizards are able to enter a fireplace at the origin building and exit a fireplace at the destination building. It can also be used as a means of communication, where magical persons can have their head temporarily transported to another fireplace to speak to those at the destination fireplace.
