Science Thingy?

could you scientificly explain the followin experiments





A match is lighted and put in a conel flask then A boiled egg is put on top of the opening of conel flask tube ofcourse it doesnt go through, but slowly it slips (the lighted match is still lighted) and eventually comes through





Exp.2


A Beaker full of a liquid(clear ,but not nesssesaryly water)is poured into another and turns fuchsia(pinky purple)





Exp.3


A 5 pound note is being soak in something and being picked uk and light by a match(ofcourse with proper equiptment)and then light on fire for a second then stops

Science Thingy?
The heat from the match expands the neck of the flask until it is big enough for the egg to pass through.





One beaker contains an acid and the other an indicator like phenolphthalein





The liquid contains a substance like carbon tetrachloride which evaporates very rapidly. It also contains something like


carbon disulfide that burns with a low energy output. The evaporating CCl4 keeps the note from burning.
Reply:i know the answer of first one...the reason is air pressure.....when the match burns inside the flask it consumes the oxygen...which causes a decline in pressure inside the flask as compared to outside air pressure....now the out side air presses the egg inside the flask which causes the egg being slipped in....
