In Olympic high-diving, athletes leap from a maximum of 10 meters above the water. Although the force of their water impact is substantial, it’s small enough that they can enter Keep reading

Brace For Impact
What happens in the moment before an object hits the water? That’s the question at the heart of a new study exploring how water deforms before an object’s impact. The Keep reading
The Two-Faced Splash
The way a sphere enters water depends on its size, speed, and surface properties. A hydrophilic (water-attracting) sphere behaves differently than a hydrophobic (water-repelling) one. But what happens when the Keep reading
Viscoplastic Drop Impact
There are many materials that don’t behave exactly as a fluid or a solid, instead displaying characteristics of both. In this video, we see drops of hair gel falling into Keep reading
Reducing the Force of Water Entry
As anyone who’s jumped off the high board can tell you, hitting the water involves a lot of force. That’s because any solid object entering the water has to accelerate Keep reading
Entrained
When an object hits water whether it draws air in with it depends on its shape, impact speed, and surface characteristics. In this experiment, though, there’s a bit of a Keep reading
