AUSTIN (KXAN) - A paper airplane does an awesome trick: flying endlessly.
The principal is the same as in real aviation: thermals. Those let real sailplanes fly for hours.
This one's on a smaller scale, of course, in the kitchen – an at-home science experiment that will be fun for the kiddos with the appropriate supervision.
The heating plates produce hot air, which rises and lets paper planes fly as long as you want to let them go.
