Bill Nye offers this mini-activity that introduces students to the topic of weightlessness as it relates to gravity and falling. Using materials found around the home (rubber band and clothespins), participants are able to create a simulation where they can observe gravity’s pull and experience weightlessness as the rubber band/clothespin system falls. While the resource provides limited background information, it does offer a brief explanation to explain to students what they are observing and the science behind it.
