A water cannon car was a device presumably designed and built by Arthur Weasley. It consisted of a water tank and hose situated on the back of a small, single person car. By 25 December, 1996, this vehicle had fallen into disuse and was dismantled, with most of the car portion buried in the ground and the water tank made invisible.
Behind the scenes
- In LEGO Harry Potter: Years 5-7, the player must rebuild this vehicle and use it to extinguish the larger fires around the Burrow. However, as the event that caused the fires in question cannot be considered canon, neither can this particular use of the vehicle.
