There’s a science experiment that’s made its rounds online and gotten people wondering about the density of lemons and limes. If you’ve seen it, you know what we’re talking about: an experiment that shows whether lemons and limes float.
All you need to do is fill two containers with a similar amount of water and choose a lemon and lime that are of a similar size. Put the lemon in the water, and it will float. Then put the lime in the water…and it will sink.
Research shows that this is because limes are just a teensy bit denser than lemons, causing them to sink in water. But why are limes denser than lemons?
That’s the topic of this post. We’ll dig into the density of limes, and why it seems to be greater than that of lemons.
Quick Answer: Why are Limes Denser than Lemons?
There isn’t any particular reason limes are denser than lemons. That’s just the way they grow naturally.
However, the increased density is very slight – both are actually almost equal in density, just like they are in other aspects.
Try This: A Science Experiment with Lemons and Limes
At the beginning of this article, we mentioned an experiment that many people have done that demonstrates the density of lemons and limes.
It’s an easy experiment. With nothing more than some water, some similarly sized containers, and a lemon and lime that are close in size, you can do the exact same experiment.
Even if you’re not interested in doing it for yourself, it could be a fun thing to show to children. It’s a great way to get them interested in science from the comfort of your own home.
All you need to do is fill the containers with water. Put the lime in one, and the lemon in the other. You’ll see the lime drop sink beneath the water, while the lemon continues to float.
You can see a video of the same experiment below.
Lemons vs Limes
We’ve compared lemons and limes in more depth in our article about the popularity of lemons and limes, but we think it’s worth examining again since we’re already talking about their density.
Lemons and limes are pretty comparable in terms of nutrition, but there are a few differences. Truthfully, lemons are a bit healthier for you.
This is because lemons have a higher concentration of potassium, protein, and fiber than limes. They are also lower in calories and carbs than limes are.
However, it’s no secret that limes are cheaper than lemons on average. If you’re looking to save a little cash, then you might want to go with limes instead.
While there isn’t a particular reason behind limes being the denser fruit, the density hardly matters. What matters more is that both lemons and limes are nutritious fruits that can give you a taste of tropical right at your own home.
