Footage of an extremely powerful hail storm battering a car in Calgary, Alberta, Canada last month. <br /><br />The video, filmed on June 30, shows the golf ball-sized stones pounding the car windscreen as the driver moves slowly along the highway. <br /><br />"It started off okay, but when we hit the highway that's when it started getting crazy," the filmer wrote online. <br /><br />"The hails impact on our car was so loud my brother and I had to yell at each other. <br /><br />"The road was covered with hail but it looked like snow and many cars pulled over to the side and we did as well. <br /><br />"We started to drive off again after it started to slow down."
