Possible Bell Ringer activity:

Imagine being able to move something just by thinking it. Scientists at the University of Minnesota's Institute for Engineering in Medicine are working on a thought-powered helicopter. Wearing a special hat, electric currents from the wearer's brain were sent to a computer that enabled a model helicopter, a quadcopter,to actually move! The scientists successfully moved the quadcopter though an obstacle course which included foam rings.
* Can you think of ways such thought technology might benefit our world?
* What might be some things you'd like to be able to move just by thinking about it?
