Let me explain the science...

When a 1000-degree heated metal ball is pressed against a pineapple, several scientific factors come into play that help the fruit resist immediate burning and damage:

High Water Content: The pineapple's high water content acts as a natural coolant. Water has a high specific heat capacity, which means it can absorb a lot of heat before it starts to get hot. This helps to protect the pineapple’s cells from rapid heating and burning.

Fibrous Structure: The pineapple's fibrous structure, which includes its tough outer rind and the internal network of fibers, creates a barrier that slows down the transfer of heat. These fibers provide insulation, preventing the heat from penetrating quickly into the core of the fruit.

Thermal Conductivity: Pineapples have low thermal conductivity, which means they do not easily transfer heat throughout their structure. This property ensures that the heat from the metal ball is localized to the point of contact and doesn't spread rapidly, allowing the pineapple to withstand the extreme temperature for a longer period.

These scientific properties combine to give the pineapple an impressive resistance to the extreme heat of the 1000-degree metal ball, making for a fascinating and visually striking experiment.
