Flashlight battery science project 64,best bicycle lights for night riding,remote flash for nikon d3000 - New On 2016

I’ve joined forces with Netflix to create a science project that shines some light on your family bonding. How many times have you tried to switch on a flashlight, only to find the batteries are dead?
The Hollow Flashlight is the invention of 15-year-old Ann Makosinski of Victoria, Canada, whom we wrote about in July. With more than a thousand submissions, the event highlights teen innovation around the world.
Fourteen-year-old Viney Kumar of Australia, meanwhile, won in the 13 to 14 age group for developing an Android app that warns drivers nearly 70 seconds before the approach of an ambulance or other emergency response vehicle.


Turkey’s Elif Bilgin, 16, was honored for a project in which she managed to create bioplastics from banana peels. Meanwhile, Makosinski wants to manufacture her flashlight with Peltier tiles, components that produce electricity when heated on one side and cooled on the other.
The LEDs are lit when body heat from a user’s hand warms the exposed tiles, while ambient air in the flashlight cools the other side.
If they can be made cheaply enough, the flashlights could help people in developing countries who don’t have access to electricity or light in the evening.
The grand prize of a $50,000 scholarship went to San Diego’s Eric Chen for his use of computer modeling to discover new flu medicines.


He used a supercomputer and biological experimentation to find ways to speed up the discovery of influenza inhibitors ahead of future flu pandemics. Aside from experimenting with the body design, Makosinski had to modify the circuit to produce enough voltage to trigger the light.
Some parents believe in an eye for an eye, a tooth for a tooth, and a Facebook post for a Facebook post.
