Have you ever played with a toy boat in the bathtub and noticed that the propeller spins and helps the boat move forward? A molecular propeller is similar to that toy boat propeller, but it's really, really tiny - so small that you can't even see it with your eyes!
Molecules are the basic building blocks of everything around us. They can be very small and simple, or they can be more complex like proteins. Some molecules have a special shape which allows them to spin around like a propeller.
These tiny molecular propellers are actually made up of atoms that are connected together like a string of beads. They spin around really fast and can move in different directions depending on how they are designed.
Scientists have figured out how to create these molecular propellers in a lab and are studying how they can be used in different scientific fields. They're not just for show - these tiny machines could potentially move things around in our bodies, help us create more efficient energy, or even be used in advanced computer technology one day.
So, even though you can't see them with your eyes, these little molecular propellers are a really exciting development in the world of science!
