Looking to build a slip ‘n slide for those hot summer days? 1: Get a box of Glad Contractor bags. They’re super heavy-duty, which guards against tearing (and crying kids). 2: Roll out the bags and duct tape them together at the seams. Tape the longer sides together to make the slide wider. Put the tape on both sides and run it the width of the slide. 3: Put the slide on a hill and use tent stakes to secure it. 4: Gently throw the hose on. Liquid soap can also be added drizzled on.
