Heather blinked. Add 3 Ltrs of sea water. nope, that was what was clearly written on the board. She sighed.

In her bag, she took her dipper and began to look for the sea water. Once she did, she scooped some water, but thought, how was she supposed to know if it was 3 liters? She ran the risk of drowning the plant or not giving it enough.

wait, the dipper she had was around one metric cup. Great, now she had to do math...how many cups does it take to make 3 liters? I metric cup is .25 liters....right...math don't fail her now...so 4 cups would make one liter...so, 3 times 4 is 12. That will make 12 cups; 12 trips to make 3 liters.

No point in complaining now; she worked on filling the tank now, making exactly 12 trips (making it 12 cups to make 3 liters) back and forth from the tank that had the sea water and her tank that had her cutting planted in the clay.

once she was done, and she was doing it rather quickly, Heather only sighed and tried to even her breathing for just a moment before glancing to the board to see the last instruction.
