Exploding Watermelons

I am gemused to read of problems in China wrt exploding watermelons.

Seemingly, as a result of using certain chemicals to promote faster growth, there has been a spate of exploding watermelons in China's eastern Jiangsu province.

The affected watermelons begin to split near the top, and within minutes burst open to reveal a jaundiced yellowish-pink flesh. In one Jiangsu town, a watermelon exploded as an elderly woman was cutting it open.

Unsurprisngly the chemicals used aren't terribly good for the human digestive system either!
