what i dont get is if i actually did this and instead of a radioactive element and a geiger counter as the trigger, it was a camera looking at a coin flipping mechanism that if it is heads, the cat dies and if it is tails, the cat lives. i wouldnt be sitting outside thinking the cat is dead and alive. its either heads and the cat is dead or tails and the cat is alive.

Sorry, but unless the box was soundproof and the cat in question was asleep, unconscious, or muzzled i refuse to believe a cat sat in a box quietly and obediantly for an hour without light, food or water. Here's how you can tell if it's alive or dead:

If it's struggling to get out or not. After an hour, yeah its dead.

Note: if I recall correctly, one point of the Schrodinger's cat thought experiment was that something on a quantum-physics level could, at least in theory, affect something on what would normally be a conventional physics level.

Okay, so we have a cat in a box. The box has a chemical weapon in it. If it goes off, the cat is dead; if not, the cat is alive. And the trigger for this weapon is whether an atom of uranium decays within the next hour... Let's assume you have no outside display for the Geiger counter that's the trigger. Then there is no way to know if the atom has decayed until you open the box.

There were, apparently, theories saying that it had neither decayed nor avoided decay — neither could happen until there was a measurement of some sort... But since the cat lives if the atom is intact and dies if it isn't, if the atom is in neither state, then neither is the cat. QED.

There are several flaws in the article, but none of them are worth going into with any depth as no one that isn't studying quantum mechanics would care or notice the difference. The reason we cannot know the momentum and position of a particle at the same time is not due to the detection method interacting with the particle. The uncertainty comes about due to the Heisenberg uncertainty principle which through a quirk of math says, the sum of the uncertainty of the momentum and the uncertainty of the position are equal to h/4pi, so you can either know one or the other or a bit of each, but the interference explanation is suitable for most, just supplying the info incase we want to be more stringently accurate.
