Eggs with no shells have to be one of the things my children find most intriguing. We made one for my 4 year old to show her nursery class last week. This fun bouncy egg experiment is great fun for kids of all ages and fascinating for adults too!
Bouncy Egg Experiment
What happens to an egg when you drop it? It smashes.
So how can you make an egg bounce?
How to make an egg bounce
Place an unboiled egg in a container of vinegar for about 24 hours. The vinegar should completely cover the egg. If you want to remove the shell faster, take it out of the vinegar every couple of hours and rinse the egg under cold water while gently rubbing away the shell.
Once the whole shell has dissolved, you have a naked egg which should bounce. Some eggs seem to break more easily than others, so you could try experimenting with different kinds of eggs to see if a certain type or size makes a difference.
To bounce your egg, drop carefully from a low height, the egg should bounce up from the surface. Can you measure at what height it breaks? Or try bouncing on different surfaces?
How about drawing a table to demonstrate your results?
If you don’t want to break the eggs, how about shrinking them? This is a fantastic way to learn about osmosis.

Key Stage 1 Science
Ask the child to predict if an egg can bounce using past experience of the properties of the shell.
Obtain and present evidence
Did you draw a table to demonstrate how high the egg bounced?
Consider and evaluate evidence evidence
Were the results as expected?
