Real World Lab preview

See inside a living body.

A 3D human body and a 3D cell that really work. Change the air, eat, run or get hurt, then watch what happens inside and find out why.

Workspace preview. Coming soon.

A body that is alive

The heart beats, the lungs breathe and blood cells go round the real circuit, changing colour with the oxygen they carry.

Try what you could never try

Breathe thin air, drink a cold drink, ride a giant wheel or fall ill. Each change runs on a live model of the body.

Always ask why

The lab reads the model and explains cause and effect, so even a mix of changes explains itself.

Down to a single cell

Open a cut-away cell, take a part out or swap one, and see what the cell does next.

New here: Build Your BodyPick your class, pick a part and fit it into a real 3D body. Turn the body any way you like as it grows, from the skeleton out to the skin.
