Play the movie to learn about fusion...
...or play with the simulations to make fusion!
In the sun, gravitational pressure keeps the particles from flying away, increasing the chances of fusion collisions happening.
Fusion occurs at critical combinations of Temperature, Confinement Strength and Particle Density.
Magnetic Confinement Fusion reactors use a donut-shaped spiraling magnetic field that traps the particles along the field lines.
