While Jane is eating a Popsicle in Jesse's kitchen, the Popsicle goes from being nearly half-eaten to whole and back again during the course of the conversation.
When Walter Jr. throws up into the pool after being given tequila he knocks the table and knocks over both of the shot glasses on the table.
In the next scene Walt sits down and both his and Hanks glasses are upright and still full.
When Jesse is cooking up some eggs for (presumably) breakfast, the first egg he cracks in the pan shows that the first egg yoke (when the shot is from underneath the pan) starts to run, whilst in the next shot, the one from above the pan, where Jesse adds another egg to the pan, you can see both the eggs yolks are still intact.
When Skyler is in the break room at work making tea, the electrical outlet on the wall behind her is empty. After Ted comes in and asks who brought the churros, in the next shot of Skyler suddenly the coffee maker and microwave are plugged in. Then, in the next shot, they are unplugged again.
At the celebration party Walt gave a speech. Then he finished and said "Thank you for coming. And enjoy." There was a change of camera shot. While Walt spoke he held a beer bottle by its neck. Half a second later, he held it by its body.
When Walt discovers the water leaking from the pipe, he's actually looking at the gas line, not a water supply pipe. Those types of heaters have all the water connections at the top.
The family has been struggling to make ends meet yet Skyler doesn't make a comment about the tankless water heater. However, getting a new water heater is now a necessary expense and Skyler might simply not know that tankless water heaters are more expensive than regular ones.
When Jesse flees his apartment after the argument with his girlfriend, he looks back on the house from the driver's seat. The camera looks through the window of a car that cannot be Jesse's, as it has a much curvier roof line.
