Transfigure a one-atom line of antimatter through the earth's crust all the way to the Wizengamot or Malfoy Manor, and then a small bubble there. His wand is then touching the item to be transformed, and it will work.

Ten points to Slytherin for creativity. Minus ten bajillion points for holy shit, are you suicidal?!

That's just 15 joules per cubic meter of rock, until you get to the bomb. Not even detectable. I wonder, however, how the magic source is going to do turning energy back into matter afterwards.

Damn. Why are people not blowing things up with antimatter all the time?

Ignorance, high transfiguration skill level required, magical safeguards in place, possibly.

Makes sense. We could probably also build a power plant powered by transfigured antimatter.

Why would the magic source do that? Wouldn't the antimatter just react with the surrounding matter and turn into energy under the laws of physics, and stay that way?

How did you get 15J, by the way?

Cube root(number of atoms in a 1m^3 cube of silicon(simplification)=number of atoms in a one atom line, assuming that the atoms were arranged in an cubic crystal(simplification). Mass-energy of those atoms, times two (for complete destruction) and then subtract for the particles that do not decay immediately (I had to look that up, I think I got about 5/6th remaining)

How would blowing up Malfoy Manor help Harry anyway? He'd be hurting Draco, who loves his father, and the court case brought by Draco against Hermione would go forward.

Are we sure of that? The trial might vanish if the House of Malfoy is extirpated.

I'm sure Harry wouldn't want to extirpate the whole House, which includes Draco. Just killing Lord Malfoy (and any servants who happened to be near) is enough collateral damage that Harry wouldn't seriously consider it if Hermione isn't facing outright death herself.

Besides, I'm pretty sure there are other branches of the Malfoys that would inherit the title. Draco mentioned an uncle or some other relative not in the line of succession who used to visit him at least a few years ago.

Even better- That uncle will likely want the title, so Harry just needs to bargain with him.

"If you get the title, you'll drop all charges, right?"

Won't save Slytherin, which is one of HP's goals.

I'm guessing that currently Hermione factors about 50 times more in Harry's utility function than the whole of Slytherin House put together.

Hermione is much more important, but HP would prefer a plan that did not inherently make Draco his enemy. I don't think it is much of a stretch to think exposing Malfoy Manor to anti-matter would make Draco become an enemy.

Only because she's in more and more immediate danger. It might be possible to build another plot to help Slytherin later, but Hermione needs help now.
