10 Science Experiments ideas for your own science party

Bubble blowing experiment

With this experiment, you can discover how bubble blowing works with children. You can experiment with different mixtures and materials to make the best bubbles and understand the science behind bubbles, such as surface tension.

Rocket Launch

Build a rocket and launch it. Using baking soda and vinegar, you can create a chemical reaction and launch a rocket. This experiment can be used to teach children about chemical reactions and the science behind launches.

Magic Milk

By adding dish soap and food coloring to milk and then dipping a cotton swab in the mixture, you can create patterns and colors in the milk.

Crystal formation

Learn about the science behind crystal formation. By mixing salt solutions and water and then allowing it to evaporate, children can grow crystals and create different shapes.

Balloon Inflation Experiment

This experiment is simple, but fascinating. Fill a balloon with a little baking soda and add some vinegar to a bottle. Place the balloon over the opening of the bottle and let the baking soda fall into the vinegar. The balloon will inflate due to the reaction of baking soda and vinegar.

Homemade Volcano Eruption

By mixing baking soda and vinegar in a bottle with dye, you can create a chemical reaction that looks like a volcanic eruption. Hide the bottle or dish in a paper mache volcano made by children.

Slime Experiment

By mixing glue and borax solutions (contact lens solution), you can make a sticky and elastic slime that you can stretch and play with.


A quiz is a great way to test knowledge of science. Come up with some fun questions about technology and science and let children compete in groups against each other.

Inventors’ Race

This is a competition where children compete in teams to make the fastest and best invention. Each group is given the same materials and a certain amount of time to build their invention. The inventions are then judged on creativity, functionality, and presentation. For example, building a cardboard and wire rocket, or letting them build something with Lego.

Build Your Own Bridge

This is an experiment for older children and requires the problem-solving skills of children. Build your own bridge using skewers and marshmallows. The goal is to build the strongest bridge that can hold the weight of different objects.

Create Your Own Circuit

Also an experiment for older children and handy parents. By building a simple circuit with a battery, a light bulb, and a wire, children can see how electricity flows and how circuits work.
