I would like to show for some students from high school, how calculate a egg's volume from a easy way, I thought in use Archimedes principle, but I don't now if this is the better way.

Any sugestions?

Take a prismatic container and fill partially with water (in such way we can fully submerge the egg without loosing water), then measure the difference of the water level after the egg has been submerged inside the container. From here we can determine the volume from the area of the container $A$ and the difference in height for the water level that is

$$V=Acdot Delta H$$

Just a variant on gimusi's answer: Take two kitchen measuring cups. Fill one with $250$ml of water. Place an egg in the other. Pour water over the egg until the second cup is filled to the $250$ml level. Measure what's left in the first.

Even better, if you have a pair of one-liter measuring cups: Put as many eggs as will fit below the liter line of one cup, then pour in water from the other. Measure what's left in the other, then divide by the number of eggs. This provides a side lesson on error analysis. (Also, I'll leave it as an exercise to figure out what to do if you only have one one-liter measuring cup and one $250$ml measuring cup.)

Finally, if your measuring cups are in fluid ounces instead of milliliters, and/or you want an answer in cubic inches, you'll have to do the appropriate conversions.
