It means trying to reverse a situation or action that has already been done, but is now difficult or impossible to change. Just like a genie that has been released from a bottle cannot be put back in, once something is done or said, it cannot be undone.
If the cover of a reagent bottle is placed on a table with the bottom down, it can pick up material from the table which would contaminate the contents of the reagent bottle after the cap is put back on the bottle.
To put a water bottle on a water dispenser, simply lift the bottle and place it on the designated area on the dispenser, usually on the top. Make sure the bottle is securely in place to avoid spills or leaks. Follow any specific instructions provided by the dispenser manufacturer for best results.
to use less water when flushing
Air inside the bottle expands when the bottle is heated. Some of it leaves the bottle until the pressure of the heated air remaining in the bottle equals the pressure of the air in the room. The balloon is then placed over the neck of the bottle and prevents any more air from entering or leaving the bottle. The air inside the bottle cools to the temperature of the ice water. The cooler air inside the bottle takes less space (volume) than it did when hot, so it sucks the balloon inside the neck of the bottle. Air pressure inside the bottle causes the balloon to stretch and enlarge until the air pressure inside the bottle, including the air in the balloon, has the same pressure as the air in the room.
One way to get it out is to brace the bottle or have a buddy hold it. Throw two or three loops of cotton string around the neck of the bottle (a shoe lace works well). Holding the ends of the string tight, with a sawing motion, pull the string back and forth.After about 3 to 4 minutes of this, the friction of the string will have heated the neck of the bottle, causing it to expand and release the (colder) stopper. Before you put the stopper back into the bottle, grease it lightly with stopper grease or petroleum jelly. Don't put a cold stopper into a hot bottle.DO NOT USE ANY OTHER METHOD to heat the neck of the bottle. The heat of an open flame, for instance, cannot be controlled and it may cause the bottle to explode or crack.A (quicker) variation is to wet a cloth with water from the hot tap (about as hot as you can stand when you wring it out - but no hotter), and wrap it round the neck of the bottle or decanter.
No , "Pandora's Box" can never be closed .
It's the genie is out of the bottle, not if. It's similar to Pandora's Box - once you start something, it's very hard or impossible to put everything back and try to start over.

It's a way of saying that once you open something up, it's hard to put everything back inside again. You've "opened" a confrontational situation or a tough conversation. A genie is a magical being that was often shown as being trapped in a bottle. Once you let it out, you weren't going to trap it again very easily.
To put a glass bottle cap back on, simply place it on top of the bottle neck and press down firmly until it clicks into place. Make sure to align the cap with the threads on the bottle neck to ensure a secure fit.
