Kids love exploring eggs, and this engaging science project gives them a chance to gain knowledge about eggshells.
This experiment with vinegar produces a rubbery and bouncy egg, providing children an opportunity to observe chemical reactions and osmosis that occur when an acid dissolves calcium carbonate shells.
Let’s find out how to make a bouncy egg!
1. Soak the Egg in Vinegar
Egg in vinegar experiments provide children with an engaging way to learn about egg structure, chemical reactions and osmosis – as well as practicing scientific method by writing down observations!
First, place a raw egg into a jar. Next, pour enough white vinegar into it so that all of it has submerged the egg completely.
As the egg sits in vinegar, a chemical reaction takes place between calcium carbonate in its shell and acetic acid present in vinegar; this causes it to dissolve and bubble away, leaving behind a clear rubbery membrane.
This strength of membrane allows an egg to survive drops from even moderate heights without shattering, creating its characteristic “bounce-back effect.” This gives rise to its appearance of being like a rubber egg!
2. Rinse the Egg
An egg’s protective bloom prevents bacteria from invading its inner content and, when left undisturbed, may remain intact for weeks or even months after being laid.
As soon as an egg becomes dirty, it should be rinsed and refrigerated to reduce foodborne illnesses. According to David Coufal, food safety professor from Colorado State University. this process should involve washing it using water that is at least 20 degrees warmer than its shell’s temperature.
Warm water combined with soap helps remove contaminants that have built up on an egg’s surface. But it is crucial that this water does not contain bacteria as this will push back into its pores of shell and may spread.
3. Bounce the Egg
A bouncer is a large person employed in bars, pubs and discotheques who is responsible for throwing out drunks and troublemakers as well as keeping those considered undesirable from entering. Additionally, they oversee “Wannabe Lines”, guest lists and dress codes in these establishments.
Bouncer jobs require well-rounded skills that combine personality with physical prowess. As such, this career path is highly sought after, and employers tend to hire those who possess substantial training and experience as bouncers.
With this simple science experiment, it is possible to transform a raw egg into a bouncy ball. Ideal for young children looking to discover what happens when an eggshell dissolves.
4. How to Make a Bouncy Egg Summary
Kids will enjoy creating a bouncy egg using vinegar in this fun science experiment! They will gain knowledge about osmosis and egg membranes while having lots of fun doing so!
Begin this experiment by placing a raw egg in a glass jar and pouring white vinegar until the entire shell has been submerged, this will allow calcium carbonate from its shell to dissipate into solution.
Allow the egg to soak in vinegar for several days; this will allow its acids to gradually wear away at its outer shell until only its insides remain visible.
After several days have passed, take out your egg from its jar and rinse it with water to rid itself of vinegar and allow the membrane to come to the surface.
