First Day Adding Dye!

We worked hard on lighting...

With reflections

Optimized for no reflections in the sand

We learned that our solution on the high side did not have enough flow to become well-mixed quickly.  We'll be working on that next week.  Marbles to reduce water in side column? a pump in the tube?  More holes in the PVC? a spinny toy?  It's looking promising....

No injuries today?
