if you are talking about a can, and why the top pops up, like i think you are, it is because of the increased presure inside the can/ bottle/ jar/ whatever.
The fulcrum is that point where a lever is fastened to a stable point. Usually it is in the middle of the lever (as when you pry the lid of a paint can) but it can be at the end (as in the case of a bottle opener). When the fulcrum is at the end, the force that results is in the same direction as the force you apply; you lift up on the bottle opener and it lifts the bottle cap up. When the fulcrum is in the middle, the resulting force is in the opposite direction to the force you apply; you push down on the prybar and the paint can lid goes up.
it means he's itching or showing off.
Simply because the metal lid expands quicker than the glass jar - making it loose. The lid will return to its original size when it's cooled back to room temperature.
It is like a planes wing, it causes the molecules on the top of the lid to want to "run" away from the burning steam, so they move vertically away. Some of those molecules will have some sort of slight attractive force with the lid, wether it be magnetic or so on, and if enough of them have enough attraction to the lid, then it will lift up

i think they are streamlined because their legs are pushed by the air which lifts them up and which causes them to jump/bounce.
