Lemon boats were a surprise discovery and are a delightful addition to water play

When you live in the Sacramento region of California, a Summer day is often over 100 degrees.

The skies are bright blue, you wear short sleeves, and each day, you wonder if this will be the day you melt into a puddle.

Because our Summers are hot, we get creative with ways to stay cool, which often includes copious amounts of water play and lemonade. Water play is available every school day, and it’s always a center bursting at the seams.

🍋 Related: Lemon and watercolor science is a must-try lemon activity!

Lemon boats float in a large, blue tub and kids pour, lift, and scoop the lemons.

We discovered lemon boats on a scorching summer day after juicing what felt like 700 trillion lemons

On this day, we juiced many lemons and then had giant bowls full of lemon peels.

What could we do with these peels instead of just throwing them away? They were small, smelled good, and looked like little boats.

On this day, lemon boats were born.

How to make lemon boats

Juice your lemons, toss them into a shallow container of water, and you have instant play at your fingertips.

It’s a delight observing the kids filling the lemons with water and watching them sink, trying to find each lemon boat’s missing half, and chatting with each other about what they are doing and seeing.  

Encourage kids to see how many toys a lemon boat can hold before it sinks. Explore using different items of different weights. For example, a lemon boat might be able to hold six family counters, but only two rocks. This is an excellent science exploration of buoyancy. 

💡 Teacher Tip: My mom juices a whole Costco-sized bag of lemons at a time and freezes them in ice cube trays. This way, she can pop a cube into her water whenever she wants, and we can make lemon boats in any season.

Kids reach into a large, blue bin filled with lemons and people figurines. A girl in a tie-dye shirt smiles and has both hands in the water.

Are lemon boats a sensory activity?

It sure is! Basic water play connects the sense of sight, touch, and sound, also known as a multi-sensory experience. 

When you look at these photos, can you imagine how the water feels? Can you hear the sound of dropping a lemon into a water table? YOU know how it looks and sounds because you have touched water and lemons many times in your life, and for kids, this is how they build their foundational knowledge.

And it gets EVEN BETTER.

When you add the lemons to this, you also add the sense of smell and possibly even the sense of taste (especially if you’re making lemonade beforehand).

Lemons smell fresh and inviting, and they elevate a regular water table to an irresistible one, just like that.

A child smiles and holds two lemon halves, one with a small blue figurine inside.

Don’t be in a rush to end the lemony water fun

At the end of your play session, dump out the water (you can use it to water your plants!) and gather all your lemons. If you put them in the refrigerator overnight, they’ll be as good as new to go again the next day.

We use our lemon boats for about a week before they eventually get tossed. Feel free to toss them out if you notice they rip apart.

Lemon boats are EVERYTHING

They smell good. They float. They’re perfectly sized for little hands.

They give extra life and purpose to something that would have otherwise been thrown away!

What’s not to love?

Frequently Asked Questions

Can I use other citrus fruits?

Absolutely! Oranges, limes, and even grapefruits work well for this activity. Just keep in mind that some fruits may be heavier or have thicker rinds, which could slightly affect how they float.

Do lemon boats actually float?

Yes! Lemons naturally float due to their porous rinds, which contain air pockets. When you hollow them out and turn them into boats, they stay buoyant—making them a fun and easy water play activity.

What’s a fun way to extend this activity?

Try adding food coloring to the water, creating small “islands” with sponges, or even making a mini regatta with multiple boats!
