A US mom got more than she bargained for at America's largest water park when she set up to film her family on a wet ride.<br /><br />In the video, filmed on July 26, 2015, at Noah's Ark Water Park in Wisconsin, the filmer sets up with her GoPro and waits for her family, who are on a roller coaster water splash. But the filmer underestimates the power of the wave as the car comes near, and the wave sends her flying backwards. <br /><br />Writes the filmer: "I had the GoPro ready to catch my family blast into the pool of water below, not thinking I should brace myself with one hand ... WHAM! The wave of water knocked me back about 10ft and there were people everywhere! No one was seriously injured, I just walked it off."
