Make a DIY Electric Lighter with Just a Few Parts
Much like the cigarette lighters in your car, you can make your very own electrical lighter with just a few tools. Essentially, all of the devices use a length of metal filament to act as a resistor in the circuit. The metal heats up as a result of the current flowing through it, allowing you to instantly light materials on fire. Check out how to make the simple yet cool device in the video above.
