Turns Out, Spiders Use Electricity to Fly

The video explores the phenomenon of spider rains, where spiders use silk threads to fly. Initially thought to be wind-driven, recent studies suggest spiders use atmospheric electricity to lift off. Experiments show spiders can fly without wind, using electric fields. This discovery could help predict spider rains and understand spider ecology better.

What natural phenomenon involves spiders using silk threads to fly?

• Spider migration

• Spider rains

• Spider weaving

• Spider nesting

What new theory about spider flight was introduced by researchers at the University of Bristol?

• Spiders use solar energy to fly

• Spiders use water currents to fly

• Spiders use atmospheric electricity to fly

• Spiders use magnetic fields to fly

What did researchers use to test the theory of spiders flying using electricity?

• A magnetic field generator

• A vacuum chamber

• A wind tunnel

• A special chamber with no electric field or air movement

What did the researchers observe when they induced electric fields in the chamber?

• Spiders changed color

• Spiders started weaving webs
