My girls were in awe by this egg experiment and honestly, so was I!  Wow the entire family this fall using nothing more than what you likely have on hand.  Are you ready to see how?

HOW TO MAKE GHOST EGGS

Materials
Method
  • Begin by filling a glass or jar 3/4 of the way with roughly equal parts of tonic water and vinegar.

  • Then, carefully place the desired amount of uncooked eggs into the jar.  You can make one ghost egg, or try this experiment using many eggs at one time.  Just be sure that the eggs are fully submerged.

It is now time to observe.

THE GHOST EGG EXPERIMENT

  • Have kids visit the jar often over the next few days, being sure to note any changes.  What do they think is happening inside the jar?  Journal their predictions.

  • Almost immediately you will notice that the egg(s) are bubbling inside of the jar.

  • You will notice the eggs bubbling throughout the experiment.  I wonder why?  What else might the kids notice?

  • After 2-3 days the eggs will be ready for exploration.  Carefully remove them from the jar. What you will discover are completely shell-less, ghostly eggs that GLOW!

So cool, right?  But why? 
Why does the shell disintegrate from the egg, and why do the eggs glow?  How does the egg stay in tact without a shell?  The answers are in the science!

WHAT happens to the shell?
  • The shell literally disappears!  The eggs don't look translucent.  They ARE translucent!

  • The vinegar completely dissolves the eggshells, leaving only a ghostly membrane behind.

WHY does the shell disappear?
  • The acidity in the vinegar breaks down the outer shell of the egg, but it leaves the eggshell membrane in tact.  To read a full scientific explanation on why the vinegar dissolves the shell of the egg go here.

WHY do the eggs glow?
  • Tonic water is "the secret ingredient" that gives these eggs their glow.  Read more on the science behind why tonic glows here.
