Erupting Watermelon?

I bought a watermelon this morning, brought it home, washed the outside, and left it in my dish rack while I ran some errands. While I was out a small piece of rind blew out and there is now a large pool of slightly grayish liquid on my kitchen counter. I've put the melon in the sink, where it continues to exude a steady stream of foamy liquid, obviously under pressure. It doesn't smell too great either. Does anyone have a clue as to what might be going on?

  1. It sounds like fermentation to me. Cut it open and check.

      Oh, yuck, no.

      Toss it, toss it, toss it. Who knows what horror is in there ... it's bleading foamy grey liquid ... that would be enough for me to get it out of my house as quick as possible.

      Who knows what other cooties are in there ... don't take pictures, don't cut it, take the financial loss ... GET IT OUT OF THE HOUSE NOW !!!

        Where's your sense of adventure? I'd love to know what's inside. I suspect it's just starting to ferment which is why it's foaming. But it could be some interesting bacterial infection which got in through an opening.

        1. re: cheryl_h

          Yeah, how about posting on Home Cooking for a recipe for 'stinky watermelon'.

    2. That sounds weird, like maybe the melon had a small puncture and bacteria or wild yeasts got in? I have never seen the like! That I am one who is not really squeamish about somethings, that would have me pitching it.

      1. It's telling you to throw it out. In fact, it's positively yelling at you.

            Amen! This I've got to see! And er...try to get a refund on it.

              Yes, pictures, pretty please? I'm fascinated...

              So tell us...how does the story end?! We want to make sure you're still alive and cooking...

            2. re: Katie Nell

              I, too, had an exploding watermelon after purchasing it one day earlier.

                Thanks for posting this picture and resurrecting this thread!

                My family and I had some good laughs at the posts.

                1. re: pagesinthesun

                  After putting a knife in it, it exploded like a can of biscuits and tore in half. One side looked like a tongue sticking out of it and the other side looked like an upside down heart. Millions of dollars to be made on eBay thrown in the trash. Lol.

                   
            3. Since you brought up watermelons........I planted some seedless ones in the garden for the first time. They look like the typical grocery store kind, the big oblong type. They're growing nicely, but how do I know when to pick them?

                When they start exploding, it's past the time to pick them.

                According to the Old Farmers Almanac it is a lot like picking a watermelon in the market ... thump, check color, look for creamy spot on the bottom, look at the size.

                However, there is a point in the 9 ways to know when to pick your watermelon that has to do with this topic it says ...

                "Check the tendril. If it's half-dead, it could mean that the watermelon is nearly ripe or ripe. If the tendril is fully dead, it could mean that anthracnose or some other fungus killed the melon ... "

                So maybe the OP has a melon with anthracnose or some other fungus

                On the other hand it could be a vampire watermelon which this article says they "stir all by themselves and make a sound like 'brrrl, brrrl, brrrl!' and begin to shake themselves."

                Did you notice a spot of blood on the melon? It tells you what to do to get rid of the vampire.

                1. re: Hoss

                  My folk wisdom on watermelons says:
                  --wait for the stem to start to wither (in reality, doesn't always happen before the melon is overripe)
                  --look at the melon's belly (the part on the ground). When it goes from greenish-white to creamy yellow, the melon is ripe. In some varieties, the skin stripes appear on the belly when the melon is young but fade after it ripens.
                  --thump it; a nice solid resonant thunk indicates a ripe melon, rather than a muffled thud.

                2. Take it outside before you cut it open. But I definitely want to see pictures...

                  1. Cut it open but duct tape your mouth shut before hand in case there is an Alien inside.....

                    1. This is the best laugh I've had all day!

                      1. I'm torn between telling you to patent it (I love alcoholic drinks made with watermellon juice) or dump it. Let us know whatever you do as it's a quite interesting phenomena.

                          Oh boy, Watermelon wine in a to-go container. Take it back and get a refund and buy a quality alcoholic beverage with the money you get back plus a little from your pocket.

                          I recently got some fermenting dried apricots at Costco. What kind of yeast could ferment in the presence of that much potassium metabisulfite is beyond me.

                            Some people once thought the world was flat and you'd fall of if you sailed too far.... :-)

                        2. Sorry, no pics -- my husband happened upon the scene, and drawing my largest knife, advanced upon the foul fruit. Informing him that he was responsible for any resulting mess, I prudently slipped around the corner into the dining room. Comes an incredibly loud sucking sound, then silence... I deemed it safe to go have a look at this point (although the bad smell was pretty strong). The inside of the melon had three large crevasses running through it, presumably where all of the liquid had been percolating. I assume that when the liquid oozed out, a vacuum was created -- thus the sucking sound when my husband cut into it.

                          I mentioned this odd occurrence to a melon vendor at the farmers' market this morning. He said that he once had a melon explode in the back of his pick-up. He agrees with Candy's theory: either a tiny puncture or a worm hole let yeast or bacteria in, the somehow resealed itself until the pressure inside the melon got too high, at which point the hole opened up again and the the mystery liquid started foaming out.

                          I'm really happy that I didn't cut into that thing when I first brought it home; wouldn't want my kids to have to explain to their kids one day that poor old granny got done in by a watermelon!

                          At present, I'm eyeing my purchased-from-the-farmers'-market-just-this-morning specimen with a great deal of suspicion as it rests innocently on my kitchen counter.

                          Be careful out there: You never where danger lurks.

                            Dang! I was really hoping to see this phenomenon! Oh well... makes for a good story!

                              1. Please be very, very careful. Sigourney Weaver had this same thing happen to her on a spaceship and I hate to tell you what 'popped' out.

                                1. You heard a giant sucking sound, knew there were such things as vampire melons, and didn't rush in immediately in case your husband needed rescuing?!?!

                                  I'm just so glad you posted an ending to this suspense. What a great laugh.

                                  By the way, my MIL has had fruit explode and a hundred fruit flies bursted forth. <<shudder>>
