For the weather balloon payload, it was made out of cardboard. The materials we have used to build the payload was styrofoam balls, two different types of duct tape, string, hot glue gun. To make sure I secured everything carefully so the pennies wouldn´t fall out. I have duct-taped the front and sides of the box and added string over it so it could protect the payload safe and secure. My weather balloon payload could resist from the 35 ft drop.
