I remember a science project in grade 8.

The people used a couple of eggs (3 all together) and 2 types of toothpaste.

They had the eggs sitting in vinegar for some extended period of time.
2 of the eggs were brushed daily. A different toothepaste on each one, the brands are irrellevant because my point is that the eggs with toothepaste were not as brittle or weak as the egg that was sitting in vinegar without toothpaste applied to it.


The moral of the story.

Don't put eggs in vinegar.

Oh ye...

And if you don't like toothpaste you can kick it old school.

Use Baking Soda, that's the key ingrediant in toothpaste...
which is why toothpaste also makes a keen stain remover on clothing and counters.
