Thankfully they included videos of everything! You can find the article here, and I'll go over the two videos in my post, commenting on each solution they attempted. Indeed, I'll also take a different route here, and instead rate their solutions instead of simply discussing them.
Bazooka: I'm not sure why they thought this would work, but it was hilarious, and we got to see the power of the bazooka...which took out the cat, house, and a nearby tree. 4/10
Squirtgun: A really great and amazing idea that didn't seem to work. Cats hate water, right? This one either didn't mind it...or the angle of the shot meant he wasn't actually being hit by it. Hmm. I'm hoping for the latter, as out of all the complex and interesting interactions and reactions of objects...cats hating water is pretty simple. Even though it didn't work, it was a great idea. 8/10.
Pyro: Holy shit I couldn't stop laughing. Yes, ok, this is a GREAT way to solve the level. I'm damn impressed the cat KNEW the house was in trouble and jumped off almost immediately. You'll also notice the house didn't just get destroyed right off...it burned long enough for Maxwell to enjoy the blaze. Very creative, very hilarious, and you're lucky the pyro didn't kill everyone by burning them alive. It was entertaining! 10/10
Escalator: Pretty decent idea here. Better than simply "stairs" or "ladder", though not much more creative beyond that. I do like how Maxwell didn't have to do any work in climbing. I also laughed at how it's constantly going up, so Maxwell ended up having to jump off of it. Not bad. 8/10
Mouse: A very traditional solution, but an average one at best in terms of creativity. We all know cats love mice. Still, he gets a bumps in score because the cat ran off the house on her own without any interaction from Maxwell. That's pretty cool. 7/10
Baseball: Yawn. Yeah, it worked, but you had to throw it a couple of times and EVERYONE will try that one out. 2/10
Battleship: ...holy shit. I...I...what? I'm blown away by this idea. The previewer was quite creative here, as the level said "No weapons"...but the battleship is a vehicle, not a weapon. It just so happens to have a cannon on it which destroys the bottles, the stand, and itself, in one big explosion. But hey, he got the starite! 11/10
Kangaroo: Alright, I didn't think the above could be topped. But...it was. This is the single most fucking hilarious thing I've seen in a Scribblenauts video. Hands down. He attaches lettuce to a fishing rod, then the rod to the head of the kangaroo...the resulting "carrot on a stick" chase causes the 'roo to plow down the bottles. Incredible. Amazing. It took some REAL creativity to pull that off. 20/10
Phew, alright, now I'll take off my judging hat. Best part about all of this is that they plan on doing this all over again every Friday right up until the release of the game. Now this is a pretty good way to spoil the game for yourself, so if you're looking to avoid that then definitely stay away.
But for everyone else this serves as a GREAT way to show off the power of Scribblenauts. We see boring solutions, solutions that definitely don't work, and creative solutions, and hilariously entertaining and incredibly awesome solutions.
That IS the definition of Scribblenauts. Glad to see IGN understands, and I look forward to next Friday and hopefully two new videos!
