What happens when your rocket fuel is magnetic force? Our latest video shows you how to make a rocket using super strong rare-earth magnets, skewers, ball bearings and blu-tack. Check it out in slow-mo and watch for something rather curious… when the magnets move down the track, momentum is added until the final ball flies off at a velocity much greater than the initial ball which starts the process.
Safety: Ask an adult to supervise this activity. Wear safety glasses when using these rare earth magnets. If they collide together hard enough, chips of magnet can fly off them. Also be careful when handling the magnets, as they can pinch your skin. Keep magnets out of reach of small children and pets.
Happy DIY-ing! If you try this, let us know how you go in the comments section here or on YouTube. If you’re in the classroom, there are teachers notes available here with Australian Curriculum links.
