Jak se pozná čerstvé vejce

Máte v chladničce vajíčka a přemýšlíte, jak dlouho už tam asi jsou. Poradíme vám jednoduchý trik, jak poznat, jestli je vejce čerstvé nebo už vám tam leží pár týdnů. Jak tedy na to? Je to velmi jednoduché.

 

 

Jak na to

Napusťte nádobu (nejlépe průhlednou) vodou. Teď vložte vejce do nádoby. Co udělá? Je několik možností, podle stáří vejce.

Pokud je vejce čerstvé leží na dně.

Se stářím se postupně zvedá, až se postupně staví na špičku. Když stojí ve vodě na špičce je staré 2-3 týdny.

Pokud vám vyplave na hladinu, znamená to, že už je staré.

Čím to vlastně je?

 

Jak vejce stárne, zvětšuje se vzduchová bublina pod skořápkou.
