Exciting Science Experiments Using Common Household Supplies

July 20, 2023

Are you looking for some engaging and educational activities to do at home? Look no further! In this blog post, we will explore seven fun science experiments that you can conduct using items you likely already have in your house. Get ready to unleash your inner scientist and embark on a journey of discovery with these hands-on experiments. 

1.   Baking Soda and Vinegar Volcano 

One of the most iconic science experiments, the Baking Soda and Vinegar Volcano, never fails to amaze. To create your volcano, you'll need a small plastic bottle, baking soda, and vinegar. Simply place the bottle in a tray, add some baking soda into it, and pour vinegar over the top. Watch as the mixture fizzes and creates an exciting volcanic eruption. 

2.   Balloon Inflation with Lemon Juice 

Did you know you can inflate a balloon using lemon juice? For this experiment, gather a lemon, a bottle, baking soda, and a balloon. Squeeze the juice from the lemon into the bottle, then carefully attach the balloon to the bottle's opening. As the citric acid in the lemon juice reacts with the baking soda, carbon dioxide gas is produced, causing the balloon to inflate before your eyes. 

3.   Homemade Lava Lamp 

Create a mesmerizing lava lamp right in your own home. Fill a clear container with water and add vegetable oil to it. Next, drop in a few drops of food coloring and observe as the colored drops move through the oil and water layers. For an extra touch, add an Alka-Seltzer tablet to create a bubbling effect, resembling a lava lamp in motion. 

4.   Egg in a Bottle 

Challenge yourself with the Egg in a Bottle experiment. Start by lighting a piece of paper on fire and quickly place it inside a glass bottle. Immediately cover the bottle's opening with a peeled hard-boiled egg. As the flame extinguishes, the air inside the bottle cools down, creating a partial vacuum that pulls the egg into the bottle. Witness the egg magically slip inside the narrow opening. 

5.   Density Tower 

Uncover the fascinating concept of density with a homemade Density Tower. Grab a tall, transparent container and fill it with liquids of different densities. Honey, dish soap, water, vegetable oil, and rubbing alcohol are excellent choices. Carefully pour each liquid, one by one, into the container and observe as they form distinct layers due to their varying densities. Marvel at the beautiful color gradient you've created. 

6.   Mentos and Soda Geyser

Prepare for an explosive reaction with the Mentos and Soda Geyser experiment. Open a bottle of soda (diet soda works best) and drop a few Mentos candies into it. Quickly step back and watch in awe as the soda shoots out of the bottle in a foamy geyser. Remember to conduct this experiment outdoors or in a large container to avoid any mess. 

7.   Rainbow Fireworks 

Who said you need actual fireworks to see a colorful display? Light a white candle and hold a piece of clean, dry white paper above the flame (but not too close). As the flame burns, it produces soot that collects on the paper, forming a black residue. Over time, the soot creates beautiful patterns resembling fireworks in various shades. Enjoy this mini firework show in the comfort of your home. 

Science experiments can be exciting and educational, and you don't need fancy lab equipment to conduct them. With just a few common household supplies, you can embark on a journey of scientific exploration right at your kitchen table. These seven experiments will engage your curiosity, spark your imagination, and provide a hands-on learning experience for both children and adults. So gather your materials, get ready to have fun, and let the scientist within you come to life!
