"A containment field?"

"Or a box or array of some sort," the Hufflepuff shrugged, "I'm not picky."

Theo just shook his head, "what kind of experiment is this?!"

"The only kind worth running," a smile, "one likely to expload in my face."

He groaned at Daphne, "she's being facetious, again!" Daphs just stared at her in awe and horror. "Why would you even need a containment field?!"

"You're from an, old, family, Theo. Surely you've come across books that don't like to be read? But, needs must."

A sigh, "...how bad is it?"

"Worse."
