- Description
- In order for the projector to work, the light from the arc lamp must be focused into a single beam. To do this, we need a monocrystal. Can you help me find it? Without it, we cannot project a beautiful starry sky.
- Completed
- You have found a great monocrystal! With it, your projector beam will be thin and powerful. If you add the right amount of chromate ions to the monocrystal, you can even create lasers!
