The Sum of all your Particles
The premise sounds simple enough: take the wooden particle apart and then try to rebuild it without sneaking a peek at the solution. But watch out, recognizing spatial relationships and spotting the solution is about as easy as seeing an atom, particle, cell or molecule with the naked eye! Each measuring six inches in diameter, these extra-large, science-inspired brainteasers for older kids or grown-ups will put your gray matter to good use. Each puzzle has a different concept and difficulty level. Once you've completed the Atom, the Molecule poses the next challenge, and then the Particle will stump you. Up for the ultimate challenge? You can tackle the Cell. And you thought passing chemistry was tough! Made in China.
