What Is the 'Protecting Plants with Ice' Technology That Prevents Them from Dying in Subzero Temperatures?

A science YouTube channel, The Action Lab, explained orchard frost protection with a freeze experiment.

The key idea is that when supercooled water freezes, it releases latent heat and keeps the plant surface near 0°C.

This is why sprinkler frost protection can shield flowers and fruit from frost damage in orchards.

The mechanism was demonstrated with experiments and thermographic imaging, making the physics easy to see.
