Have you heard of an LED Throwie? People are talking about them. Making them is simple. All you need is an LED(a flashing LED works best), a 3V cell(battery), a strong, tiny magnet and some tape. All of these can be purchased easily. Check out my website, www.myledpassion.com/simplest-led-flasher.html for all of the details on what they are and how to make them. They are so simple and fun, and anyone can make them. No experience necessary.
