1. Baking Soda Volcano
This classic experiment is a favorite for a reason. It’s a fantastic way to get kids excited about science while also letting them unleash their creativity. Building the volcano is half the fun, and the eruption never fails to impress. It’s an explosive way to spend quality time together and spark curiosity about chemical reactions.
Ingredients:
- 1 small plastic bottle
- 1 cup baking soda
- 1 cup vinegar
- Red food coloring (optional)
- Dish soap (optional)
- Playdough or dirt to shape the volcano
Steps:
- Preparation: Place the plastic bottle in the center of a large tray or baking sheet to catch any spills.
- Building the Volcano: Use playdough or dirt to shape a volcano around the bottle, leaving the top open.
- Adding Baking Soda: Fill the bottle halfway with baking soda.
- Color and Foam (Optional): Add a few drops of red food coloring and a squirt of dish soap to the bottle for a more dramatic effect.
- Eruption Time: Pour vinegar into the bottle and step back to watch your volcano erupt!
Safety Tip: Since the eruption can be messy, wear safety goggles to protect your eyes and do this experiment outside or in an easy-to-clean area.
Fun Fact: The reaction between baking soda and vinegar creates carbon dioxide gas, which causes the bubbly eruption!

2. Invisible Ink
Playing spy is a timeless activity for kids, and what better way to do it than with invisible ink? This simple experiment lets kids write secret messages and then reveal them using heat. It’s a magical experience that combines art, science, and a bit of mystery.
Ingredients:
- Lemon juice (from 1 lemon or bottled)
- Q-tip or small paintbrush
- White paper
- A light bulb or iron
Steps:
- Prepare the Ink: Pour a small amount of lemon juice into a bowl.
- Write Your Message: Dip the Q-tip or paintbrush into the lemon juice and write a message on the white paper.
- Drying: Let the paper dry completely. The message will be invisible once dried.
- Reveal the Secret: To reveal the message, hold the paper close to a light bulb or carefully iron it on low heat (adults should handle the iron). The heat will make the lemon juice oxidize and turn brown, revealing the hidden message.
Fun Fact: Lemon juice oxidizes and turns brown when heated, making your hidden message visible.
3. Homemade Slime
Making slime is a gooey, stretchy way to explore the science of polymers. Kids love the tactile experience, and parents will enjoy seeing their children’s faces light up as they create and play with their homemade slime. Plus, it’s a fantastic opportunity to discuss chemical reactions and non-Newtonian fluids.
Ingredients:
- 4 oz of white school glue
- 1/2 teaspoon baking soda
- 1 1/2 tablespoons contact lens solution (containing boric acid)
- Food coloring (optional)
- Mixing bowl and spoon
Steps:
- Mix Glue and Baking Soda: Pour the glue into a mixing bowl and add the baking soda. Stir well until they are fully combined.
- Coloring (Optional): If you want colored slime, add a few drops of food coloring and mix thoroughly.
- Add Contact Lens Solution: Gradually add the contact lens solution while stirring. The slime will start to form and pull away from the sides of the bowl.
- Kneading the Slime: Use your hands to knead the slime. It may be sticky at first, but keep kneading until it reaches the desired consistency.
Safety Tip: Avoid contact with eyes and mouth. Wash hands thoroughly after playing with the slime.
Fun Fact: The contact lens solution contains boric acid, which interacts with the glue to create a stretchy, gooey slime.

4. Balloon Rocket
Turn your living room or backyard into a space station with this simple balloon rocket experiment. It’s an exciting way to teach kids about the principles of physics, like thrust and Newton’s third law of motion. Watching the balloon zoom across the string is thrilling for kids of all ages.
Ingredients:
- 1 balloon
- 1 long piece of string (about 10-15 feet)
- 1 straw
- Tape
- Two stable objects (like chairs) to tie the string to
Steps:
- Set Up the String: Thread the string through the straw and tie each end to a stable object, like two chairs, making sure the string is taut and straight.
- Prepare the Balloon: Inflate the balloon but don’t tie it. Pinch the end to keep the air inside.
- Attach the Balloon: Tape the inflated balloon to the straw. Make sure the open end of the balloon is facing one of the chairs.
- Launch the Rocket: Let go of the balloon and watch it zoom along the string!
Safety Tip: Make sure the area around the balloon rocket is clear of obstacles to avoid any accidents.
Fun Fact: The air escaping from the balloon creates thrust, pushing the balloon forward like a rocket.
5. DIY Lava Lamp
Creating a DIY lava lamp is not only mesmerizing but also a fantastic way to explore density and chemical reactions. The colorful bubbles rising and falling in the oil are sure to captivate your kids’ attention, making science feel like magic.
Ingredients:
- 1 clear bottle or jar
- Water
- Vegetable oil
- Food coloring
- 1 Alka-Seltzer tablet
Steps:
- Fill with Water: Pour water into the bottle until it’s about one-quarter full.
- Add Food Coloring: Add a few drops of food coloring to the water and mix.
- Add Oil: Fill the rest of the bottle with vegetable oil, leaving some space at the top.
- Add Alka-Seltzer: Break an Alka-Seltzer tablet into pieces and drop one piece into the bottle. Watch as colorful bubbles rise and fall, creating a lava lamp effect. Add more pieces as needed to keep the reaction going.
Fun Fact: The Alka-Seltzer tablet reacts with water to produce carbon dioxide gas, which causes the colored water blobs to float up through the oil.
Bonus: DIY Sundial
Embrace the ancient art of time-telling with a DIY sundial. This activity is not only educational but also connects kids with nature and history. It’s a great way to teach them about the Earth’s rotation and the movement of the sun across the sky.
Ingredients:
- 1 stick or pencil
- Small stones or pebbles
- A sunny day
Steps:
- Find a Sunny Spot: Choose a sunny spot in your yard where the sundial can stay undisturbed.
- Set Up the Stick: Push the stick or pencil into the ground so it stands upright.
- Mark the Shadow: Place a small stone at the end of the shadow cast by the stick. This will be your first time marker.
- Track the Time: Check the shadow every hour and place a new stone at the end of the shadow each time. By the end of the day, you’ll have a series of stones marking the hours.
Fun Fact: Sundials have been used for thousands of years to tell time by tracking the position of the sun’s shadow.
