How do I get the egg out?

Turn the bottle upside down. Make sure the egg is positioned well in the bottle neck. Continuing to hold the bottle upside down, hold it over your mouth and blow hard into the bottle. Quickly raise the bottle up and the egg will immediately pop down out of the bottle onto your mouth. The reason is that you added so much more air pressure into the bottle than the pressure outside the bottle. The pressure inside balanced with the outside by expanding the egg out of the bottle. A second method for removing it is to put the bottle in a cold ice chest or the fridge or freezer for several minutes to get the bottle air cold. Then remove the bottle upside down, and wait patiently several minutes.
