I like to call this an anti gravity machine, but it could be called a permanent magnet levitation machine. The thing I like about it is kids are fascinated by it.
Step 1: First Gather the Materials.
1. Glass or plastic tube.
2. Glue that will stick to glass, plastic, or metal.
3. Button magnets that fit inside the tube.
4. Larger Button magnets to cap the tube.
Step 2: Assembly of the end cap.
Place a smaller button magnet on the larger button magnet and glue.
Step 3: Attach to the transparent tube.
Step 4: Stack the Button Magnets.
Stack the button magnets until the stacks are to long to turn around in the tube, then insert the stacks making sure they are polarised north to north and south to south.
Step 5: Cap the End.
Cap the end holding the button magnets with tape.
Step 6: Glue and let set.
Step 7: And You are Done.
And there you have it a permanent magnet levitation machine.
