Magnetic Rods and Balls — 52 Pieces

52 pieces: strong magnetic rods and steel balls that connect at any angle. Start with flat squares and triangles, then build up into three-dimensional frames — pyramids, towers, whole structures. The magnets make the joins instant, so a child builds at the speed they think.

How you play

1. Join two balls with a rod to make your first edge.
2. Add rods to a ball to branch out in different directions.
3. Build a flat shape first — a triangle or a square.
4. Lift it into three dimensions by adding rods upwards.
5. Keep extending until the structure is as big as it will stand.

What it builds

• Geometry in the hands — why a triangle holds and a square sags
• Three-dimensional thinking, built up from flat shapes
• Magnetism and gravity, discovered by what stands and what falls
• Design without instructions, which few construction toys allow

Three ways to play it

• Build the tallest tower that still stands on its own
• Make a shape flat, then work out how to make it solid
• Take one rod out of a structure and see whether it survives
