The metal tip of a light bulb is located at the base where the bulb connects to the socket. It is usually made of brass or another conductive material to allow electricity to flow into the bulb.
A light bulb is made out of three items. A filament produces the light, glass gives the light bulb shape and controls the brightness, and the base allows the bulb to be placed in a socket.
Remove the lava lamp by lifting up the glass. It separates from the base because it just sits in it. Unscrew the old bulb and screw another one in. When you remove the bulb you will notice that the bulb and base may not be the size of a standard household bulb. On the inside of the base, or the bottom of the base, there should be information about the type and wattage of the bulb. You need to get the same type of bulb to insure that the bulb base will screw into the socket. The wrong type bulb may not fit in the socket or the bulb may be too large and the top of the lamp will not fit properly on the base. If you get the wrong wattage, the bulb may not be hot enough or to hit to make the bulb function properly.
No, the e27 refers to the Edison screw base size of the bulb. It is a standardized designation for the type of base used on the bulb, not the length of the bulb itself.

Unavoidable in certain situations. Light fixtures are sometimes mounted in the ceiling - the bulb must then be mounted base up or base horizontal.
