I think a crocodile has two eyelid's per eye, so it can see properly in both fresh and salt water but other than that I don't know.

The air inside the tin will expand when heated causing great pressure on the inside of the can. If the pressure inside the can is greater that the force holding the lid on, then the pressure will force the lid to pop off off the can. have to heat it then and go crazy
Harriet should ask several senior citizens to evaluate whether her jar lid design is easier to use than a traditional jar lid.
Often, lids are made of metals which are great conductors of electromagnetic waves (including heat). When warm water is applied to a "difficult" lid, excitement of the atoms in the metal occurs (very slight) which causes a slight expansion. This expansion helps the lid to be moved from it's grip on the jar or bottle. This is also found in plastics. Although not through expansions. The heat from the warm water literally softens the plastic.
If the lid formed a seal, it should sag from the outside pressure.
One eye lid is stronger than the other eye lid. The bigger the fold the weaker your eye lid is.

Some animals have a third eye lid, Including some lizards and camels. The main reason for this is to offer the eye extra protection from sand and dust. As many animals live in environments where it is a true risk of being blinded by constant sand clouds, and the third eyelid, which usually goes across the way offers the eye slightly more protection.
I know of two animals that don't have an eyelid, a hamster and a goldfish.

Pick up the gerbil and push its eye lid up.
Eye Primer is applied before any other eye makeup. The primer is applied all over your lid up to your crease. The primer is to keep eye makeup on longer and to give it a better colour, instead the colour you choose to put on your lid it will appear more brighter than it would without primer. Hope this helped :) <3.
Lid = .50 Pot = 10.50 Pot is $10.00 more than lid.
The waterline is the bottom lip of your eye lid. Pull down your bottom lid of your eye and you will see the rim. That is the waterline.

A pus pocket under the eye lid can form if if there is an infection in and around the eye.
