How to Make a Simple Pulley System to Lift Things with Your Kids

Build a fun and educational pulley system at home using basic materials to teach kids about simple machines while lifting lightweight objects.

1. Gather Your Materials. You'll need a spool or empty toilet paper roll, string or rope (about 3-4 feet long), a small bucket or container, and something sturdy to hang your pulley from like a tree branch, playground equipment, or a ceiling hook. For the pulley wheel itself, you can use a real pulley from a hardware store (about $3), or make one using a spool, toilet paper roll, or even a sturdy paper plate with a hole in the center. You'll also want some lightweight items to lift like small toys, blocks, or snacks.
2. Set Up Your Fixed Pulley. Find a safe, sturdy place to hang your pulley system - a low tree branch, swing set, or indoor ceiling hook work well. If using a homemade pulley, thread your string through the center hole of your spool or toilet paper roll. Tie one end of the string securely to your hanging point, making sure the pulley wheel can spin freely. The other end of the string should hang down where your child can easily reach it. Test that your pulley spins smoothly by pulling gently on the hanging string.
3. Attach the Load and Handle. Tie your small bucket or container to one end of the string that goes over the pulley. This is where you'll place the items you want to lift. Leave enough string on the other side so your child can pull comfortably while standing on the ground. You can tie a small handle (like a stick or loop) to the pulling end to make it easier for little hands to grip. Make sure all knots are secure and test with a lightweight item first.
4. Test and Play Safely. Start with very light objects like a small toy or a few blocks in your bucket. Show your child how pulling down on their end of the rope lifts the bucket up. Let them experiment with different items, always keeping safety in mind. Supervise younger children closely and establish rules about what can and cannot go in the bucket. Never lift anything heavier than a few pounds, and never let children put fingers near the moving pulley wheel.
5. Explore and Learn Together. Once your basic pulley is working, try experiments together. Compare lifting the bucket directly versus using the pulley - is it easier? Try adding more items to see how the pulley handles different weights. You can even set up challenges like lifting a snack to a tree fort or moving toys from one level to another. Talk about how pulleys are used in real life - flagpoles, construction cranes, and even window blinds.
