Assuming you would like a tutorial on how to make a simple chute blocker at home:
You will need:
-a large plastic container with a lid (ex. an empty laundry detergent bottle)
-smaller plastic container that can fit inside the first one (ex. an empty shampoo bottle)
-hole punch
-duct tape or other strong adhesive
-scissors
-string or rope
First, clean out and dry your chosen containers. Cut a hole in the center of the lid of the larger container, big enough for the smaller container to fit through snugly. Tape the smaller container to the underside of the lid, making sure it is airtight. Next, use the hole punch to make two holes near the top of both containers, on opposite sides. Thread string or rope through both holes and tie tightly so that there is a loop handles on either side of the chute blocker. Test it out by holding it over an open garbage can and dropping small items like paper balls through—the smaller container should prevent anything from falling through!
