How to Make a flubber egg
This video shows the viewer how to make a 'flubber egg'. A flubber egg is essentially an egg which appears to be normal but is actually very rubbery and bouncy. This means that if dropped the egg will not crack – presumably the name relates to the film 'Flubber'. The egg is made by submerging it in vinegar for around 3 days. The egg should not be disturbed during this process. The egg can then be removed and dried. It should be relatively rubbery and quite bouncy. This can be a great party trick and can often create lots of confusion.
