This DIY project is not only a useful tool, but it's also a fun toy for kids and adults interested in the wonders of the human body. Despite the somewhat startling sight of the veins in your arm being illuminated, it is essential for doctors and anyone administering venipuncture to be able to locate the veins. It is also another marvelous application for LEDs.
