Introduction: DIY Science: Dara O'Briain's Science Club (Series 2) (01:43)
The Science Club team will explore a new earthquake early warning system, demonstrate new safety gear, and examine how citizen scientists are combating dengue fever.
Tracking Biological Data (04:34)
Mark Miodownik uses a variety of gadgets to track his own biometric data. He finds the monitoring personally unnerving. If enough people engage, it might help scientists find trends and links between behavior and health.
Demonstration: Lightning (02:32)
Mark Miodownik uses a Tesla coil to show what happens if a person stands too close to a tree when it is hit by lightning. Lightning always seeks the fastest way to the ground, and it can be deadly.
Demonstration: Lightning Through the Body's Core and Insulators (03:12)
Mark Miodownik uses an electric circuit and a pickle to demonstrate what happens if lightning goes through the human body. He also shows how lightning breaks down air to make a pathway for itself.
Lightning Strike Survivor (01:48)
Eric Brocklebank was struck by lightning inside a tent, as he was picking up a sausage with metal tongs. The lightning traveled down his side, across his hips, and blew out the bottoms of his feet.
Earthquake Early Warnings (03:29)
Geophysicist Dr. Elizabeth Cochran has figured out a way to make an earthquake monitoring station out of a laptop and a cheap seismometer. She has recruited thousands of volunteers to collect data and send it to a central location for processing.
Collecting Wasted Energy (02:18)
Helen Czerski demonstrates technology that collects human energy to power lights. It has the benefit of collecting energy where and when it is needed.
Makers and Hackers (03:38)
Mitch Altman defines hacking as taking what exists, improving it, and sharing it. The hacker community is reclaiming and democratizing innovation. Mark Miodownik hacks a webcam to make a microscope.
Make a Difference via Hacking (02:18)
Dr. Aldo Faisal demonstrates a robot arm controlled by eye movement. Commercial eye-tracking systems are very expensive; Faisal built a cheap one using cameras from a game console.
Beet Box (02:54)
Mark Miodownik and Dara O'Briain play with vegetable drum kit built using a tiny, cheap computer that measures capacitance. This is also how touch-screens work.
Demonstration: Airbag (02:57)
Scientists had the idea for the airbag in the 1950s, but it took several tries to create a working version. Now airbags work via a chemical reaction, set off by an electrical impulse.
Demonstration: Airbag Helmet (01:57)
Now that airbag technology is in good shape, it can be repurposed. A group of design students used it to create the hovding, an airbag for bicyclists.
Dengue Fever (02:12)
Dengue fever is the fastest growing mosquito-borne disease in the world. There is no vaccine and no cure, and it can be fatal. Wiping out the mosquito population is the only solution.
Breeding a Self-Destructing Mosquito (01:45)
Dr. Luke Alphey genetically modified mosquito eggs to produce offspring that wouldn't survive to adulthood. To fight dengue fever, scientists needed a way to pass that trait on.
A research team created an antidote that would keep the modified mosquitos alive long enough to breed. Dr. Andrew McKemey releases them in areas where mosquito control is needed. In some areas, the team has wiped out more than 80% of the mosquito population.
Guest Entemologist (02:02)
Dr. James Logan joins the Science Club team to discuss the pros and cons of controlling mosquitos via genetics. He brings moquitos to bite host Dara O'Briain.
The Science Club team discusses self-experimentation and the many well-known scientists who have engaged in it. Team members filter Thames river water and drink it.
Technology and Possibility (02:59)
The Science Club team explains that the games industry and ubiquitous technology are driving forces behind cheap, democratic science innovation.
