The Cell Puzzle
Let's not beat around the bush ? The Cell could have been called 'death by puzzle' until it was decided that perhaps this wasn't a very nice name for a prezzie! The shape is unpleasantly complex. The holes go right through the wooden triangular blocks and this makes the structure even more tricky to rebuild. Embark on it at your peril!
Also in the Lab Test range is the Molecule, Particle and Atom; only humans were lab tested in the development of these products.
