Most of us still think of Slinkys as toys. But they have their serious side, too. The springy steel spirals have been used to build everything from radio antennas to light fixtures and pecan pickers. Physics teachers use them in class to demonstrate cool stuff like – wave properties – forces – and – energy states.
The Slinky has even made it to the big screen, in the “Toy Story” movie series.
Time’s up. It’s time for us to slink away.
