... Seriously. 2am. Nope, just no. Kat wouldn't even dare try to stay up that late, even if her life depended on it. And of course, chocolate frogs made people a bit hyper so... that might explain Lex's attitude most of the time. "You probably had a lot of chocolate frogs today." Because that was Alexa Cambridge and chocolate frogs. Nothing else could compare.

Blast a chunk off the wall. To be honest, that made Kat laugh a bit. Not in a bad way, but because thinking of it was amusing. Could you imagine two girls whacking their heels on the cave's wall? That'd be priceless, but Kat considered that though just in case their other options didn't work. "My shoes have heels," she nodded. So they might use her shoes. What Kat could imagine after this task, is her shoes all broken and useless. She could fix that with Reparo though, so she was willing to break her heels anytime now. But just to give it a try, you know. Summoning something wouldn't be bad. "Accio stone," Kat said with an arch hand movement.

And Lex had a point. Most of the potions had the same measurement for water. "Yeah, 500 millimeters." Lex had the honours of filling up the cauldron though. Kat didn't mind and she peered in the cauldron too. Yeah, that looked just about 500 ml now. They didn't have a measuring cup or whatever useful measuring tool in here so their best option was to trust their instincts. As for the 5 grams, Kat nodded too. "Five grams is equal to one heaping tablespoon." The Slytherin visualized it in her head and made sure that later on, she'd estimate that too. However, she still hoped that measuring cups would fall out of the sky.

Getting things lit up and boiling. "Aren't some of the leaves flammable?" Just because, well, they were surrounded by herbs and plants. "That plant over there..." Kat pointed at the long and evergreen ones. "It looks like a palm." Was it a palm? The Head Girl looked at Lex for verification. Kat knew that palm leaves were flammable and capable of starting a fire, so maybe that would be helpful?
