What you get
Build a pulley system and experiment with mechanical advantage! Assemble a pulley-powered crane that can spin around, raise its arm, and lift loads. Then swap pulleys in and out to see first-hand how mechanical advantage makes it easier to lift things.
Includes a step-by-step video tutorial link, illustrated blueprint instructions, all the materials, and a special-edition Tinker Zine magazine to learn more about the power of pulleys and simple machines!
this was a fun crate, my daughter liked it a lot!
I loved how interactive this project was once the crane was completed. You could change the amount of pulleys on the crane for more versatility and was overall easy to assemble. A great tool to teach my child how a pulley system works and occupied him for hours as he experimented with different items around our house.
This crate was super entertaining after completing the project. So many great experiments were possible -- my husband and son had so much fun doing different challenges seeing how heavy an item could be before the crane tipped over while lifting. My son was so proud of his accomplishment!
