Why Your Watermelons May Hold The Risk Of Exploding
By C.A. Pinkham
Sometimes, watermelons can unexpectedly explode and coat your walls with debris from internal pressure caused by fermentation.
As fruit ages, it starts to ferment, and bacteria break down all the sugars they can, converting them to alcohol. This process introduces carbon dioxide inside the melon.
Similar to shaking a soda can, this can lead to explosive ruptures from the pressurized buildup. The issue can also resolve itself when a crack forms and slowly releases the gases.
While it's not entirely preventable, you can mitigate the problem by storing the watermelon in the fridge to slow down the process. If it's foaming, get rid of it immediately.
Heat exacerbates the issue, and the only real way to deal with this issue is to monitor your watermelons closely.
