Never heard that I always thought vinegar made it rubbery
A hard boiled egg will sink in water because it is denser than water. However, it will float in vinegar due to the lower density of vinegar compared to the egg.
To make a bouncy egg, place a raw egg in a glass of vinegar for 24-48 hours. The vinegar will dissolve the eggshell, leaving the inner membrane intact. The membrane will make the egg bouncy when dropped from a low height.
You get a hard boiled egg, and put a hole in it.
To make an egg bounce, carefully lower it into a container of white vinegar and let it sit for 24-48 hours. The vinegar will dissolve the eggshell, leaving the egg with a rubbery membrane that allows it to bounce when dropped from a low height.
Vinegar will dissolve the egg shell. Salt water will not do anything.
The egg will become transparent and also the shell will become rubbery. :-)
4-5 days
the outside of the egg will be hard because the egg will be boiling
If you put newspaper under it, it cushions the egg and causes the egg to survive.
To get an egg into a bottle without breaking it, heat the air inside the bottle by lighting a piece of paper inside. Quickly place the egg on the mouth of the bottle, allowing the hot air to escape and creating a vacuum that pulls the egg into the bottle.
You put a flaming match inside and the egg on top. The egg will automatically go inside.
if you spin it and put your finger on the hard boiled egg it would stop
