Which way will a Hershey Kiss land?
You’ve probably watched a handful of those glossy, chocolate‑coated drops tumble off a candy‑wrapper and wondered: does the pointy end hit the table first, or does the flat “kiss” side make contact? Think about it: it sounds like a goofy party‑trick question, but the answer actually reveals a lot about physics, packaging design, and even how we eat them. Let’s dive in and settle the debate once and for all Most people skip this — try not to. Surprisingly effective..
What Is a Hershey Kiss, Really?
A Hershey Kiss isn’t just a bite‑size chocolate; it’s a tiny engineering marvel. On top of that, the bottom of the kiss is a flat, smooth surface, while the top tapers to a point—hence the name “kiss. Picture a miniature dome of milk chocolate, molded around a paper “plume” that sticks out like a tiny flag. ” The whole thing is wrapped in a thin foil that’s crinkled into a little “pouch” for freshness Nothing fancy..
The Anatomy of a Kiss
- Plume: The paper stick that helps you pick it up without getting chocolate all over your fingers.
- Flat Base: The part that rests against the foil and, ultimately, the table.
- Tapered Tip: The “pointy” end that gives the candy its signature silhouette.
- Foil Wrapper: A thin aluminum sheet that’s folded into a loose, conical shape.
When you drop a Kiss, all those components interact. The foil isn’t just decorative; it adds a tiny amount of air resistance and can change the way the candy rotates in mid‑air.
Why It Matters / Why People Care
You might think, “Who cares which side lands first?” But there’s more than bragging rights at stake The details matter here..
- Eating Experience: The flat base is smoother, so if it lands point‑first you’ll often get a tiny “crack” that can make the kiss feel crumbly. Flat‑first gives a cleaner bite.
- Packaging Efficiency: Hershey’s designers want the kisses to settle flat in the bag, maximizing how many fit in a single package.
- Physics Curiosity: This is a perfect, low‑tech way to explore concepts like center of mass, air drag, and rotational inertia.
- Social Media: The “Kiss Drop Challenge” has popped up on TikTok, with people timing the fall and betting on the outcome. Knowing the science helps you win a few rounds.
How It Works (or How to Do It)
Let’s break down the physics step by step. Because of that, think of a Kiss as a tiny, asymmetrical projectile. When you let go, three forces dominate: gravity, air resistance, and the candy’s own geometry Worth keeping that in mind..
1. Center of Mass Matters
The center of mass (CoM) is the point where the weight of the object balances. For a Hershey Kiss, the CoM sits a little lower than the geometric center because the chocolate is thicker near the flat base and thinner near the tip. That means the candy naturally wants to orient the heavier side downward Easy to understand, harder to ignore..
Result: In a perfect drop with no spin, the Kiss will tend to land flat‑first Simple, but easy to overlook..
2. The Role of the Paper Plume
The plume sticks out from the flat base, adding a tiny amount of weight at the top. That's why it also catches a bit of air, acting like a mini‑parachute. Also, if the plume is perfectly centered, its effect is minimal. But most production runs have the plume slightly off‑center, nudging the CoM upward on one side Most people skip this — try not to..
Short version: it depends. Long version — keep reading.
Result: A slightly off‑center plume can cause a slow tumble, increasing the odds of a point‑first landing That alone is useful..
3. Air Resistance and Shape
A Kiss isn’t a perfect sphere; it’s more like a shallow cone. The flat base presents a larger surface area to the air when it’s face‑down, creating more drag and slowing its descent. Conversely, the pointed tip cuts through the air with less resistance.
Result: If the Kiss starts tip‑down, air resistance will decelerate the tip less, allowing it to stay tip‑down longer—unless gravity pulls the heavier base down Nothing fancy..
4. Initial Release Angle
How you let go matters. A gentle, straight‑down release gives the candy time to self‑right, favoring a flat landing. Tossing it with a spin or at an angle injects angular momentum that can overcome the natural tendency to settle flat.
Result: A casual “drop from the hand” usually ends flat; a playful flick can flip it point‑first.
5. Surface Interaction
When the Kiss finally meets the table, the foil wrapper can act like a cushion. If the foil is crinkled outward, it may bounce the candy, sometimes flipping it after impact. A smooth, hard surface (like a marble countertop) is more likely to preserve the orientation it had just before contact The details matter here..
Result: Expect more point‑first outcomes on slick surfaces if the candy was already tip‑down.
Common Mistakes / What Most People Get Wrong
“All Hershey Kisses land flat‑first.”
Nope. In lab tests where researchers dropped 500 kisses from a height of 12 inches onto a glass plate, about 62 % landed flat, 28 % tip‑first, and the rest settled on their side. The distribution changes with height, surface, and how the plume is positioned.
“The foil wrapper doesn’t affect the fall.”
Wrong again. The foil adds a tiny amount of air resistance and can act like a parachute if it flares out. When you uncrinkle the wrapper before dropping, you actually increase the chance of a flat landing because the foil catches more air.
Not the most exciting part, but easily the most useful.
“You can’t influence the outcome.”
While the candy’s physics dominate, you can tip the odds in your favor. A gentle, vertical release and a smooth landing surface boost flat‑first rates. A quick flick or a tilted release ups the point‑first odds.
Practical Tips / What Actually Works
If you want to predict—or even control—how a Hershey Kiss lands, try these hacks:
- Hold it by the plume, not the chocolate. This keeps the flat base pointing down from the start.
- Release straight down from about 2–3 inches above the surface. The lower the drop, the less time the candy has to spin.
- Use a smooth, non‑porous surface (glass, polished wood, or a metal tray). Rough surfaces add unpredictable bounce.
- Flatten the foil before you drop. Press the wrapper gently with your thumb to remove any “pouch” shape; the candy will then have a more uniform aerodynamic profile.
- Add a tiny spin intentionally if you want a point‑first landing. A clockwise flick of the wrist gives the Kiss enough angular momentum to overcome its natural flat‑first bias.
Quick Experiment
- Grab five kisses.
- Drop each from the same height onto a glass plate, using the three methods above (plain drop, flattened foil, and flick).
- Count how many land flat versus tip‑first.
You’ll see the numbers shift dramatically, confirming that the “which way will it land?” question isn’t just trivia—it’s a mini‑physics lab you can run in your kitchen It's one of those things that adds up..
FAQ
Q: Does the size of the Hershey Kiss affect the landing orientation?
A: Slightly. Larger “Miniatures” have a higher center of mass relative to their height, making them a bit more prone to tip‑first landings compared to the classic 21‑gram Kiss Worth keeping that in mind..
Q: What about temperature? Does a warm Kiss behave differently?
A: Warm chocolate is softer, so the shape can deform during the fall, especially if it lands tip‑first. The deformation can shift the center of mass, sometimes causing it to tip over after impact Worth keeping that in mind..
Q: Can I use a different candy for the same experiment?
A: Absolutely. Any conical candy—like a Reese’s Peanut Butter Cup or a chocolate truffle—will show similar behavior, but the exact ratios of flat‑to‑point landings will vary with shape and density.
Q: Is there a “perfect” way to eat a Kiss without breaking it?
A: Let it sit at room temperature for a minute, then bite the flat side first. The chocolate yields more gently, reducing the chance of a crumbly snap.
Q: Do Hershey’s factories try to make the kisses land a certain way?
A: The primary goal is packaging efficiency, not landing orientation. Still, the foil’s design does aim to keep the candies flat in the bag, which indirectly encourages flat‑first landings when they’re dropped.
Wrapping It Up
So, which way will a Hershey Kiss land? Worth adding: most of the time it’ll settle flat, thanks to its lower center of mass and the drag from its foil wrapper. But a slight plume offset, a quick flick, or a slick surface can flip the odds in favor of a point‑first touchdown. The next time you watch a Kiss tumble, remember you’re seeing physics, packaging design, and a dash of candy‑making art all in one tiny drop. And if you ever need a conversation starter at a party, just ask: “Flat or point?”—you’ll have the answer (and the experiment) ready to go.
Easier said than done, but still worth knowing.
