5 Bizarre Natural Phenomena In Everyday Foods

When thinking about extraordinary foods, most minds would conjure up images of obscure cuisine, and elaborate dishes with unpronounceable names. However, remarkable secrets lie hidden in foods we eat on a daily basis, with fascinating scientific explanations behind them. From nuts to fruits, to vegetables, here are 10 Bizarre Natural Phenomena in Everyday Foods.

1. Brazil Nuts

Anyone who has ever had a container of nuts has unknowingly witnessed a strange effect that no scientist has been able to fully explain. In nearly every package of nuts, the Brazil nuts will appear at the top, with the smaller nuts at the bottom. The same applies to cereal, with all the largest cereal at the top of the box and nothing but dusty shreds all the way at the bottom. But why? Common knowledge tells us that larger nuts would sink to the bottom, with smaller nuts rising to the top. Well, nobody quite knows. Dubbed the “Brazil Nut Effect” but more professionally known as “granular convection,” this phenomena has stumped experts for years. The concept refers to when various pieces of small, similar mass objects rotate in a way similar to how fluids move.[2] The process a package of nuts goes through to get from the factory to the hands of a consumer requires lots of jostling.

When the nuts are all pushed upward, the smaller ones will fall below the larger ones, pushing them upward. This will repeat in a cycle because the nuts are continuously shaken around. However, the Brazil Nut Effect provides a slight wrinkle to this logic. See, the Brazil nuts will reach the top of the container and just stay there, thus ending the cycle. Scientists aren’t sure why they aren’t able to move from their position on top. Of course, many theories have been presented. Perhaps the nuts are too big to fit into any smaller spaces in the container after that shake, or perhaps the density of the nuts play a role in pushing it towards the surface. Either way, the science has applications beyond this nutty predicament (get it)? Dr. Douglas J. Jerolmack and his team have even found a link between this phenomenon and the reason why rivers can resist erosion, because rivers too have larger rocks near the top with sand and gravel further down in the river.[2]

2. Cranberries

Nobody would think to compare an ordinary cranberry with a popular children’s toy, but there is a surprising similarity between the two. Though commonly cooked and softened in order to reduce the natural tartness of the fruit, a raw cranberry has a very different texture. When ripe, it will be able to bounce in the same fashion as a bouncy ball. This is due to the small air pockets inside of each cranberry, as well as the firm texture that allows it to bounce up off the ground. In fact, cranberry farmers even use this as a ripeness test for their berries. It is common for berry farmers to bounce each cranberry over a wooden barrier, where the berries that clear the barrier will go into circulation, while the ones that don’t, go into separate bins to become juice. Interestingly, this was discovered by accident, when an old farmer from New Jersey known as John “Peg Leg” Webb poured his supply of cranberries down the stairs. Due to his wooden leg, this was his best method of transporting them. However, he noticed that the more firm cranberries would bounce to the bottom, while the softer and more battered berries would sit limply at the top of the staircase. This discovery took place in 1880, and farmers have been using bounciness to test cranberry ripeness ever since.[3]

3. Corn 

Corn has been around for thousands of years, yet few realize that every ear of corn has a unique similarity about it. See, corn will always have an even number of rows. This is due to the fact that a corn ear is not just a vegetable, but an inflorescence, meaning that it produces nearly 1000 female flowers. These flowers, otherwise known as the future kernels, will be ordered into rows, forming the common image of an ear of corn. An average ear of corn has 800 kernels, organized into 16 rows. The even number comes from the fact that each spikelet (basic grass flower) will produce two florets, which are the small flowers that make up a full flower head. It will produce two because one floret must be fertile while the other must be sterile. Interestingly, this applies to foods other than corn. Watermelon, for example, supposedly has a consistently even number of stripes. No matter the case, this stems (no pun intended) from the fact that a cell will always divide into two cells that in turn each divide into two more cells. As this cycle continues, the number will always stay even. How odd![4]

4. Pistachios

Pistachios may seem innocent enough, but little did we know that they have a sinister side. That’s because pistachios, when stored in large quantities, are at high risk of spontaneously combusting. It is a known fact that fat burns very easily, and each pistachio nut is nearly 50% fat. Furthermore, pistachios have almost no water in them, and if they are kept in a high-moisture area, then they become moldy. With their total absence of water and a high concentration of fat, pistachios are at risk of becoming flammable. This risk turns into reality when pistachios are packed close together in large amounts, as the oils of the nuts can heat themselves up, causing them to burst into flames. Because they can self-heat, this pistachio-fueled nightmare can occur with no warning, with no human contact. This has led to many strict guidelines as to how pistachios are shipped, as most of the world pistachio production comes from the Middle East. This means that ships are required for transport, and nobody wants to see a boat burn down from improperly packaged nuts.[5]

5. Nutmeg

Nutmeg is a spice most commonly used around the holidays, as a sweet garnish to drinks or an ingredient in desserts. However, just like the pistachio, there is a dark secret behind this festive spice. This is because nutmeg is really a hallucinogen, capable of causing powerful highs and unpleasant side effects. Sudden bursts of panic, trouble urinating, and constantly dry mouth are just a few consequences of the hallucinogenic trip. Nutmeg itself is actually a seed, and it contains a compound known as myristicin. Myristicin is used in many drugs that are used to affect mental state, and it is the reason why nutmeg produces hallucinogenic effects.

Though this may shock all of us, it wouldn’t have surprised anyone in 12th century Europe. Back then, it was considered a drug rather than a garnish, and people would use it frequently in order to induce hallucinations. It is even believed that famous physician Nostradamus ingested nutmeg in order to gain visions that led to his scientific discoveries. Nutmeg remained a popular drug for years to come, but somewhere along the way its status shifted into the innocent spice, we know it as today.[6]
