Our sister-site TouchArcade notes that Chillingo's excellent physics puzzler Feed Me Oil is free today for both the iPhone and iPad. It's normally $0.99 for iPhone and $1.99 for iPad. Feed Me Oil is something of a mix between World of Goo and Where's My Water?.

Every level features two things: A spigot where oil shoots from, and an area (usually designed as a mouth of a strange creature) where you've got to get the oil to. Completing each level involves getting the oil from the spigot to the goal area utilizing widgets you can drag into the game area. For instance, oil flows off simple platforms, it can be curved by magnets, and even blown in a different direction by fans.
Feed Me Oil was shockingly popular when it first hit last summer, so there's a decent chance you already have it. If this is the first you've heard of it though, make sure you don't miss this freebie.
Feed Me Oil is available free for today for iPhone and as an HD version for iPad. [Direct Link: iPhone/iPad]

Still a fun game, though.
Free for one day only? I think it autoremoves on the next day? Mine disappeared today...
Try downloading again? My free purchase has persisted for several days. I don't think temporarily free = temporary license to play.
Fun game, but I definitely prefer where's my water :D.
I love this application too good to pass the time.
