How a single drop of soap can propel a boat
In short: Watch as pepper flakes shoot across a plate when soap touches the water. This video demonstrates how soap disrupts the molecular bonds of water to create movement.
Comedian Rufus Hound and his son Alby explore how household substances affect the water's surface. By adding soap to a small boat made from a juice carton, they observe how the liquid pushes water out the back, propelling the craft forward. This mechanism mimics how hot gases exiting a rocket's base push it upwards.
