You watch the crystal for a minute to see if it does anything. It just
sits there. Then you remember it has something to do with sunlight.
You move the crystal to a sunnier part of the ground. It flashes again
and it seems like the grass is on fire, but the fir goes out and you
can actually see the grass growing. It must be growing at least an
inch a minute. "Wow!", you think,"This is no regular
crystal from the local jeweler!"
