Alchemist Bombs a Magical Attack?

[Dragnmoon]

Quick question, With Incorporeal in mind, is an Alchemist bomb considered a magical attack like a spell?

[TwilightKnight]

Initially, I though no because they are mixing physical, perhaps mundane chemicals. But, a review of the language in the description seems to indicate otherwise...
"Bomb(Su): In addition to magical extracts, alchemists are adept at swiftly mixing various volatile chemicals and infusing them with their magical reserves to create powerful bombs that they can hurl at their enemies." [emphasis mine]
This sounds like the bombs are definitely magical in nature.

I'd say yes. The Bomb ability is marked (Su). Plus, up in the Alchemy ability, it says:

An alchemist can create three special types of magical items—extracts, bombs, and mutagens.

If that doesn't make them a magical attack, I don't know what does. 8^)

Edit: Emphasis mine.

Sounds reasonable
