He devised a scheme to steer the balloon by suspending ropes from the basket and dragging them on the ground. The weight of the rope and the friction it generated as it dragged across the ground ...

but it actually operates on the same principle that’s at work when you rub a balloon your head. Put simply, when friction is applied to the proper materials, charges can build up enough to ...

A balloon is taped to a straw ... on the pond is very slippy and completely frictionless. Because there is no friction, running, walking and crawling are impossible. The ice is also very hard ...

Friction with the ground is one reason why ... one propelled by an elastic band around the axel, or a balloon-powered car which doesn't directly power the wheels. Experimenting with reaction ...
