This “inkless pen” works with the magic of lead. The metal lead. You know… the neurotoxic metal that poisoned the Romans, that you have to scrape out of your old house using a respirator, that you have to test your kid for?
Lead is a soft metal, so if you draw on paper with it, it’ll leave a grey line on the paper. Made out of lead. Now you’ve got a paper covered in lead.
Just in case you think I’m confused and you’re all ready to send me a mad email – no, it doesn’t use graphite, which is the “lead” in mechanical pencils. It uses actual lead.
