Lava Lamp Magic
If you’ve ever been mesmerized by the hypnotic bubbles in a lava lamp, you’ll love this simple science experiment that lets you create your own lava lamp magic at home.
You’ll need a clear plastic bottle, water, vegetable oil, food coloring, and an effervescent tablet like Alka-Seltzer.
First, fill the bottle about 3/4 full with vegetable oil. Then, add water until the bottle is nearly full, leaving a little space at the top.
Add a few drops of your favorite food coloring to the mixture. Finally, break an effervescent tablet into smaller pieces and drop them into the bottle one at a time.
Watch in awe as the tablet pieces react with the water, creating colorful bubbles that rise through the oil and then sink back down, just like a real lava lamp!
The science behind this experiment is simple: the oil and water don’t mix because of their different densities, and the gas released by the effervescent tablet is lighter than both liquids, causing it to rise to the top before the bubbles pop and the gas escapes.
Invisible Ink Messages
Want to send secret messages like a spy?
You can create invisible ink with lemon juice, then reveal the hidden writing by heating the paper or brushing it with a baking soda solution.
It’s a fun way to communicate covertly with friends and family.
Lemon Juice Ink
Secretly send messages to your friends using invisible ink made from lemon juice!
You’ll need a few simple household items: lemon juice, water, a cotton swab, white paper, and a lamp or other light bulb.
Mix equal parts lemon juice and water in a bowl. Dip the cotton swab into the mixture and write your message on the white paper. Let it dry completely; the message will disappear.
To reveal the hidden message, hold the paper close to a light bulb. The heat will cause the lemon juice to oxidize and turn brown, making your secret message visible!
The science behind this experiment lies in the organic compounds found in lemon juice. When exposed to heat, these compounds react with the air and oxidize, changing color. The reaction is invisible until the heat is applied, making it the perfect method for sending secret messages.
Try experimenting with different ratios of lemon juice and water, or even other acidic liquids like vinegar or orange juice. You can create your own spy codes and have fun exchanging covert messages with your friends!
Baking Soda Reveal
Another fun invisible ink experiment uses baking soda and water. Mix equal parts baking soda and water until the baking soda dissolves. Dip a paintbrush, cotton swab, or toothpick into the mixture and write your secret message on white paper. Let the “ink” dry completely. It’ll become invisible once dry.
To reveal the hidden message, you’ll need grape juice concentrate or any dark juice. Pour some juice into a shallow dish and dip a paintbrush or sponge into it. Gently paint over the paper with the invisible message. The baking soda will react with the acid in the juice, causing your secret writing to change color and become visible!
This chemical reaction occurs because baking soda is a base, and grape juice is an acid. When they interact, they neutralize each other and create a color change.
Experiment with different acidic juices to see which works best for revealing your invisible ink messages. You can even try making your own pH indicator using red cabbage juice to test the acidity of various liquids and reveal hidden baking soda messages.
Secret Spy Communication
Elevate your invisible ink experiments to the next level with these secret spy communication techniques.
Combine 1/4 cup baking soda with 1/4 cup water to create your invisible ink solution. Use a cotton swab or paintbrush to write your message on white paper, allowing it to dry completely. To reveal the hidden message, paint over the paper with grape juice concentrate or a mixture of 1/4 cup rubbing alcohol and 1 tsp turmeric. Watch in amazement as your secret communication appears before your eyes!
For an even more discreet method, try using a white crayon to write your message on white paper. To uncover the hidden text, paint over the paper with watercolor paints. The waxy crayon resists the paint, making your message visible.

Floating Egg Experiment
Have you ever wondered why some objects float while others sink? With the Floating Egg Experiment, you’ll discover the science behind buoyancy and density using everyday household items. You’ll need a raw egg, a tall glass, water, and salt.
First, fill the glass about three-quarters full with water. Gently place the egg into the water and observe what happens. You’ll see that the egg sinks to the bottom.
Now, remove the egg and add about 6 tablespoons of salt to the water, stirring until it dissolves completely.
Place the egg back into the glass. You’ll be amazed to see that it now floats! The salt has increased the water’s density, making it denser than the egg. Objects float when they’re less dense than the liquid they’re in.
Try experimenting with different amounts of salt to see how it affects the egg’s buoyancy. You can also test other objects to determine their density relative to water.
This simple experiment demonstrates the fascinating interplay between density and buoyancy, key concepts in understanding the behavior of objects in liquids.
DIY Lemon Battery
Discover the power of electrolytes with this simple DIY Lemon Battery experiment! You’ll need a lemon, two different metal objects (like a copper coin and a zinc nail), and a small LED light or multimeter.
First, roll the lemon on a hard surface to soften it up, then make two small cuts in the fruit about an inch apart. Insert the copper coin into one cut and the zinc nail into the other, ensuring they don’t touch each other inside the lemon.
Now, use alligator clip wires or regular wires to connect the positive end of your LED light or multimeter to the copper coin, and the negative end to the zinc nail. If using an LED, you should see it light up! If using a multimeter, you’ll measure a small voltage, typically between 0.9 and 1.0 volts.
