Five Divers

A new Cartesian diver variation that utilizes differences in buoyancy for an awesome twist.

We’ve found an awesome new science activity that uses Cartesian divers. No, it’s not Hook or Squidy, although they are pretty awesome, too. We’re talking about the Five Divers experiment. This project features, you guessed it, five individual Cartesian divers, but they’re all in the same bottle. Give the bottle a squeeze and watch as more divers sink as the pressure increases. Try it for yourself!
