  • How to make an affordable 'Vein Finder', for use during venipuncture

    Dear Alex,Thanks first of all the wonderful idea. I was wondering if you could help me out I am made the vein finder so I can enter a high school science competition however I have a problem. It works and I bought the same exact material as you except mine cannot locate any veins. Like when I project it on an arm there are no black lines or anything!! Can you please suggest how I can fix it!!!
