Corrected entry: Look at the neighbor's wife while the father is saying, "super glue?" She's mouthing his lines.
Corrected entry: When the group is whistling for Quark in the backyard, Ron reveals that he cannot whistle. In the scene right after the lawn mower incident, the group tries to get the attention of Mr and Mrs Szalinski, and Ron whistles incredibly loudly.
Corrected entry: From what I gathered, the machine compresses the empty space between matter, which in turn shrinks the object in its path. So the mass of the shrunken object is still the same, meaning the weight is also the same. This would mean that their weight on such a small area would create extreme pounds per square inch pressure on anything they step on, causing them to press through the wood, burrow into the ground, etc. They would probably need snowshoes to overcome this. Plus Rick Moranis could not sweep them away and put them out to trash, since the weight of them alone would easily exceed 400 pounds.
Corrected entry: During the scorpion/ant fight scene, the ant and scorpion are close to the same size. In reality the scorpion would exceed the ant by many times. The ant wouldn't be able to fight it, and the scorpion probably would hardly notice it was around.
Corrected entry: When the kids are riding along on the bug when they are shrunk, if you look really really closely you can see a member of the crew pulling it.
Corrected entry: When the kids find one of Nick's legos in the yard it is very clear that it is only 2 holes up and 1 across. However when the scorpion atacks there is a shot from behind the lego brick and it has 3 holes up and 2 across.
Corrected entry: The kids are swept up into the dustpan and subsequently end up in the rubbish bag at the end of the garden, but when they cut open the bag to peer out they are clean as a whistle, not a speck of dust on them.
Corrected entry: Nick says "we're about an inch tall" and yet the ant, which is only a baby ant, is much longer than any of them.
Corrected entry: If the beam of the laser shrinks the first thing it hits, then why wouldn't the following string of events happen? 1. The kids' shirts shrink, since they are in immediate contact with the "laser." 2. The shirts would shrink and tear instantly since the kids are still wearing them. (And if the girl's bra is in the path of the "laser," that would be interesting to see!) 3. Then, since they are now in a direct path of the "laser," they would shrink, leaving them naked from the waste down. 4. Their first mission would be to free themselves from their clothing lying on top of them.
