Watch these drops roll and bounce as they make their way around and around this Spiral Timer. This 5 inch liquid Spiral Timer will make you just want to watch it over and over again. The little oil droplets roll down the spiral "staircase" and it continues for about 5 minutes! Once all the droplets reach the bottom just flip it over and you'll start the drops rolling and dropping again! This Spiral Timer makes a fun way to study the scientific principles of liquid density and hydro-dynamics and it's just plain relaxing to watch!
Incredible Science Fun Learning Ideas:
- Discuss density and how oil and water don't mix.
- Discuss other liquid with different densities than oil and water.
- Explore hydro-dynamics and how it applies to everyday life.
