Two words: Wacky Wire.
You know, that game with the spinning metal coil. You have to guide a metal ring over the spinning wire all the way to the bottom without touching. Most people find this to be almost impossible. I find it to be super easy. Here are a couple tips:
1. Kneel down. You want to be eye-level with the bottom of the wire, because that's where the only tricky part is. The top of the wire is simple if you do it slowly.
2. Grasp the wand just outside the ring, not at the ends of the wand. The closer your hands are to the ring, the less likely you'll make extraneous movements that will cause you to lose.
Try these. On 7/10 I won 2 out of 3 times and walked out of SFGAm with a huge killer whale (close to 6' in length) and a giant octopus. The whale barely fit in my fairly large Oldsmobile, and I couldn't fit the octopus in, so I had to give it away, which made someone's day.
