Building a Liquid Density Tower

Are you looking for a fun science activity to do at home? Building a Liquid Density Tower is an amazing way to see cool science concepts in action using everyday household items!

The Experiment

What exactly is happening when you do this experiment? The secret lies in a mix of physics, chemistry, and engineering principles. By following a few easy steps, you can create a fascinating reaction or build a neat little device.

What You’ll Learn

• The Science: You’ll see real-life scientific principles like chemical reactions, density, or forces at work.
• The DIY Aspect: You’ll build and prepare everything yourself, using common materials.
• The Conclusion: Observation is key in science—watch closely and see what happens!

Pro Tip: Always have an adult help out, and make sure to ask questions along the way. “Why did that happen?” is the most important question in science!

The FIRST® Connection

Did you know that playing around with simple home experiments is the first step to becoming a real engineer or scientist? If you enjoyed learning about how this works, you’ll love FIRST® Robotics!

In programs like FIRST Tech Challenge (FTC) or FIRST LEGO League (FLL), students take these basic concepts—like friction, electricity, and material properties—and use them to build actual, competitive robots. It is like taking your home science experiments to the absolute next level!

By joining a team, you transform your curiosity into real hands-on engineering experience. Check out FIRST Inspires to find a local team or start a journey in robotics today!
