Скачать или смотреть Fallon Invention Audition - Mikalah's Stop Rocking on Your Chair Invention

Mikalah's little brother Samuel has a big problem!
He won't stop rocking on his chair.
So Mikalah has thought of an invention which she has called 'Stop Rocking On Your Chair!'
The invention makes a loud buzzing noise and bright light when it detects a chair rocking.
Mikalah and her Dad have now made the invention and it works really well. The switch in the device which detects the rocking is basically a small glass tube containing mercury metal. Mercury is a liquid metal which conducts electricity. The mercury flows to the contact points when the chair rocks.

This episode on 'Science for Kids' is the audition video for a segment on the Jimmy Fallon Talk show called Fallonventions.
