Crushing Flowers Dipped in Liquid Nitrogen #Chemistry When flowers are dipped in liquid nitrogen, the water inside their cells freezes almost instantaneously, forming sharp ice crystals that damage the cell walls. This rapid freezing causes the flowers to lose their flexibility and become extremely rigid and brittle. As a result, when the frozen flowers are touched or crushed, they shatter like glass. This demonstrates how extreme cold can dramatically alter the physical properties of biological
