Anti-Gravity (Puzzle Potato)

Isaac Newton gave the world the law of gravity — but legend says he also worked in secret on its opposite: antigravity. In 1680 a fire started by his dog Diamond destroyed much of that hidden research. Centuries later, a mysterious object said to have belonged to Newton surfaced at auction, and rumour holds it conceals his lost discovery. Your task is to open it: free the acrylic beams, position the metal balls against the right symbols, find the tiny pyramid-key and work your way through to whatever Newton sealed inside.

• Birch wood, acrylic and metal parts, 93 laser-cut pieces — a real sensory mix of sliders, beams, magnets and metal balls
