Dumbledore's description was crucial. As soon as he finished, Andrew had an idea.
"Should we make a Deep-Sea Breathing Potion to keep everyone safe?"
Andrew pushed his food aside and put forward the suggestion.
"Or we could simulate a vacuum and make a potion that lets people survive in it. In theory, that shouldn't be too hard."
He looked at the other headmasters, a little uncertain.
After all, he had yet to develop a potion of his own, one that bore his name. His greatest innovation so far had been adjusting parts of existing potions to better suit the way he worked.
In theory, though, it should not be too difficult. Compared with potions like Skele-Gro or Liquid Luck, a potion that kept a wizard's blood from boiling, prevented heat loss, and stopped the wizard from bursting in a vacuum hardly seemed all that challenging.
Existing potions already had similar effects. They just needed to be strengthened and combined.
"It doesn't sound that difficult, and a potion would be more reliable. We can also try casting spells tailored to the problem," Karkaroff said, his voice far less cloying when he spoke normally. "The more preparations we make, the safer it'll be."
"We'll take charge of developing the potion," Madame Maxime said with a nod. "I can't promise we'll succeed, but I'll find as many reliable wizards as I can. We'll use that deep-sea exploration excuse from earlier."
"Then we'll work on improving spells that might help," Karkaroff said, picking up the thread. "I can't promise they'll be particularly useful, though.
"After all, no one's studied anything like this before."
"We'll find a way to get more spacesuits. We're designing a large device anyway." Headmaster Vladislav showed no embarrassment. His side had put considerable effort into the preliminary research and the
