Know H2O

Dear terrorists,

Bomb tunnel, flood city? Really? Let me let you in on a little physics secret: water generally does not flow up. It's true. Sure, blowing up the Holland Tunnel would make for a major mess -- death, traffic issues, mental issues with tunnels, etc. -- but flooding the Financial District it would not. The river sits below the land here in NY, just like it probably does where you live.

Oh, and in the event that the Financial District did flood? We own these things called pumps. They suck the water out of an area that has water in it and dumps it somewhere else (like back in the river). It's amazing.

Thanks for being such idiots.

Sincerely,
Me
