ELI5: What is the Bose Einstein Condensate

Reading the wikipedia article didn't really help me get the full picture. What is it, how do you get to temperatures that low?

Bose–Einstein condensate is a state of matter, like solid or liquid, that happens when certain types of particles called bosons are made to have low energy. Basically this means "made really cold", close to absolute zero (0K or -273°C), which is the coldest temperature possible.

A Bose–Einstein condensate has 0 viscosity, which means it is as slippery as you can possibly be. Because the particles have such low energy, instead of them bumping around randomly like in a liquid, the particles all move in an identical way. This is called a "giant matter wave".

To get to this very cold state, scientists usually trap particles in strong magnetic fields to keep them from moving too much, then use lasers to push them around and slow them down even more.
