COMPLETE 10-PIECE PULLEY SYSTEM & NO LOST PARTS: This comprehensive mechanics physics kit includes everything you need: 2 fixed pulleys, 2 movable pulleys, 2 durable ropes, and 4 hooks. It comes completely packed in a sturdy, transparent storage case for easy organization, transport, and mess-free classroom management
HEAVY-DUTY METAL CONSTRUCTION FOR SAFETY: Unlike flimsy plastic alternatives that crack under pressure, our pulley blocks are crafted with premium heavy-duty iron brackets and smooth-rolling metal wheels. Built to withstand rigorous daily use in middle school labs, they ensure accurate force reduction experiments and guarantee student safety when lifting weights
MASTER "SIMPLE MACHINES" VISUALLY: This block and tackle pulley system is the perfect STEM educational tool to intuitively demonstrate mechanical advantage, tension, and kinetic energy. Students can easily set up single, double, or compound pulley configurations to visually see how machines reduce the effort needed to lift loads
FLEXIBLE SETUP WITHOUT BULKY STANDS: Our flexible hook-and-rope design allows teachers and homeschooling parents to hang the pulleys anywhere from classroom crossbars to home door frames. It offers unlimited combination options for various science fair projects, making setup quick and effortless
IDEAL STEM GIFT FOR SCHOOLS & HOMESCHOOLING: Whether you are setting up a middle school physics lab, conducting a science project, or engaging in home education, this interactive teaching equipment makes learning mechanics exciting. An excellent gift for future engineers and science enthusiasts
