Making Self-Assembling Wires That Find Their Way Through a Maze
Cool science alert: They look like tiny snakes trying to find their way through a sea of castor oil.
If you love science experiments where the sheer awesomeness of our Universe takes your breath away, you're in for a treat. In this video by The Action Lab, you can learn how to make self-assembling wires that can find their way through a maze.
The Action Lab is full of simple to complex experiments executed by an engineer, and all of these experiments show how exciting science can be. As for this one, he first gets a petri dish and then puts some aluminum foil around it. As the next step, he adds castor oil in the middle and pours tiny balls of steel. Then, he proceeds to explain what's going on and demonstrates what happens when he charges it to an extremely high voltage. The visuals are pretty interesting and will give you something to think about today.
