Author: Rose Novotny  |  Last Updated: 13 July 2023

London kids parties are a perfect opportunity to combine fun and learning, and what better way to engage young minds than with exciting science experiments? In this blog post, we’ll explore a variety of hands-on and engaging science experiments that will not only entertain children but also spark their curiosity and foster a love for science. From explosive reactions to mesmerizing chemical reactions and amazing physics demonstrations, get ready to create a party atmosphere that is as educational as it is entertaining!

Fizzy Fun: Mentos and Soda Geyser

Create a dazzling and explosive reaction by combining Mentos candies and soda. Set up a safe outdoor area, place a roll of Mentos candies in a tube, and drop them into a bottle of soda. Watch as a geyser of fizzing soda erupts into the air, delighting the young partygoers. This experiment demonstrates the rapid release of carbon dioxide and provides an exciting introduction to the principles of chemical reactions.

Oozing Slime: DIY Polymer Fun

Get hands-on with a DIY slime-making experiment. Mix together glue, borax, and water to create a stretchy and gooey polymer slime. Encourage children to explore the fascinating properties of polymers by stretching, twisting, and molding their slime creations. This experiment allows kids to explore the science behind non-Newtonian fluids while enjoying the tactile sensation of slime.

Bubbling Potions: Volcano Eruption

Create a volcanic eruption using simple household ingredients. Build a volcano structure using paper mache or clay, leaving a cavity at the top. Fill the cavity with baking soda, then pour in vinegar. Watch as the mixture fizzes and foams, simulating a volcanic eruption. This experiment demonstrates the chemical reaction between the baking soda (sodium bicarbonate) and vinegar (acetic acid), creating carbon dioxide gas and a bubbling effect.

Magic Milk: Colorful Surface Tension

Explore the fascinating properties of surface tension with the magic milk experiment. Pour a thin layer of milk into a shallow dish, then add drops of different food coloring to the milk. Dip a cotton swab in dish soap and touch it to the milk’s surface. Watch as the colors swirl and mix, creating mesmerizing patterns. This experiment showcases the interaction between the soap molecules and the fat molecules in the milk, breaking the surface tension.

Rainbow Density: Layered Liquids

Create a colorful and visually stunning display by layering different liquids based on their densities. Pour liquids such as water, oil, and colored syrup into a transparent container, one at a time. Watch as the liquids form distinct layers, each with a different density. This experiment introduces the concept of density and buoyancy, as well as the importance of observing and understanding the physical properties of substances.

Hovering Balloons: Static Electricity

Amaze the young partygoers by demonstrating the power of static electricity. Inflate balloons and rub them against different materials like wool or hair. Hold the balloons near lightweight objects, such as small pieces of paper or aluminum foil. Watch as the objects are attracted to the balloons, seemingly hovering in the air. This experiment showcases the transfer of electrons and the creation of static charges.


Science experiments provide a perfect blend of fun and education, making them an excellent addition to London kids parties. From the explosive Mentos and soda geyser to the mesmerizing magic milk and colorful layered liquids, these experiments engage young minds and spark curiosity about the world of science. By incorporating hands-on activities, children not only enjoy the thrill of discovery but also develop critical thinking skills and a passion for learning. So, get ready to ignite their scientific curiosity and create a party atmosphere that is as educational as it is entertaining!
