1 of 62: From June 24-26, 2011, Discovery Green is home to a supersized sprinkler as part of Target's mission to 'Make Summer Funner.' Entrance is free. Just bring a swimsuit to Discovery Green's Jones Lawn. But the giant sprinkler isn't the only fun activity that kids and families can enjoy to cool off during the hot summer months in downtown Houston. (KTRK Photo/ Gina Larson)
