Okay, step one--check. Step two. What's step two? Zara looked up again and read aloud to herself, "Take one of the small tanks and fill the bottom with 30 cm of clay." With her gloves still on--which was there ever since the beginning--Zara got the tanks and clay from the back of the class. Why didn't she just get all the stuff she needed so that she wouldn't have to be all over the place and be over with it? Right, because her mind wasn't working well. Still walking like a drunk, Zara held the small tank carefully, and the clay.

'What's step two again?' she thought to herself. She forgot again. Reading the instruction written on the board, Zara finally remembered and filled the bottom of the tank with clay until it measured up to about thirty centimeters.
