Steve Spangler Science: Light Writer

With an LED as your pen and light as your ink, you can write a message on a camera screen.

Writing in the dark is challenging. After a letter or two, it gets messy and the message is lost. Even something as simple as your name will look like you were writing in an earthquake. It’s especially tough when you have to write backwards and you can’t see the letters. It takes a combination of steady hands, backwards thinking, and technology to get to a phenomenal writing experience!
