Journey to the Center of the Earth Hints
How can I polish the rough crystal?
1 of 4: That strange contraption inside the crystal cave will polish it. There are several interactive spots on that piece of equipment.
2 of 4: The rough piece of crystal fits nicely on the right pedestal.
3 of 4: Some bellows are attached on the far left side. Clicking on them will blow whatever is inside the glass container onto the crystal.
4 of 4: Click the sand on the glass container. Then click on the bellows 4 or 5 times. It will change shape when it is finished. Remove it and look at it in inventory. Make sure it is called a "piece of polished crystal."
