Today we put a fun twist on one of our favorite science experiments and made GHOST EGGS!
My girls were in awe by this experiment, and honestly, so was I! Read on to see how you can WOW your family with this simple twist of science.
- Raw eggs
- A jar or container
- Tonic water
- Begin by carefully placing the desired amount of eggs in a jar.
- You can make one ghost egg or try this experiment with many eggs at a time.
- Fill the jar with roughly equal parts of tonic water and vinegar being sure to fully submerge the eggs.
- I used more vinegar than tonic water to ensure that the desired results would be achieved, but I don’t think that it matters too much.
Now, it is time to observe.
- After roughly 48 hours have kids remove the eggs from the jar.
The shell literally disappears! The egg does not look translucent. It is translucent! The vinegar completely dissolves the eggs shell, 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, but why? Read more on the science behind how that works here.
My kids were in awe by this experiment and thought the GHOST EGGS were the coolest! Get your littles excited about science, and give this magical experiment a try!
