[Dada Guest Post] MaryAnne was able to capture this stunning picture of Emma holding a glowing green lollipop. It is even more eerie in real life, and a very fun laser science for kids activity!
What you don’t see in the first picture is me aiming a green laser ponter at the lollipop.
Emma made the discovery that the laser can make her lollipop glow on her own. Under very close and careful supervision (since shining a green laser into your eyes can cause blindness), I let Emma experiment with my green laser pointer. She took her lollipop that she still had around from Halloween and pointed the laser at it. Even in a completely lit room, the lollipop glowed green! This is a great example of light refraction. You can test light refraction through different substances – how does water differ from a lollipop? How about wooden blocks?
We’re now going to grab Johnny and Lily and learn more about lasers together from the MIT lectures available on YouTube:
