Einstein Tube – Hydrophobic Sand (ML)
- In stock, ready to ship
In Einstein Tube – Hydrophobic Sand by Purple Cow, kids experiment with a special kind of hydrophobic sand that barely gets wet. Pour it into water, scoop it back out and see how different it is from regular sand. This simple science experiment is a fun way to explore surfaces, materials and how they react to water.
Children can run several tests: shaping sand under water, burying and rescuing tiny objects, or comparing normal sand and hydrophobic sand side by side. The compact tube makes it easy to store, carry and set up quickly at home, in classrooms or during STEM clubs.
This Einstein Tube – Hydrophobic Sand is for you if you enjoy hands-on materials, quick experiments and surprising visual results. It’s a great way to spark curiosity and introduce basic STEM thinking.
Created by Purple Cow, the Einstein Tubes line offers bite-sized science activities that are easy to use and perfect for young budding scientists.
