Laser Science for Kids: The Glowing Lollipop

Experimenting with lasers and lollipops

[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:

  1. What a fun way to learn about light. JDaniel got a light saber lollipop for Christmas. When you pressed a button on the handle, a small light at the base of the lollipop glowed and lit up the whole lollipop.

    How neat! We haven’t explored much w/ lasers, but the kiddos got a snap circuit kit for Christmas, and it’s been a big hit around here!!

    Great photos! I love that she’s learning AND having fun. My daughter got some snap circuits for Christmas so we’ve been using those. And, not related, but we played your drawing game on Sunday, where you draw the bottom half of something and then the top. My girls loved it!

    What a neat discovery! And that bird embellishment on her shirt looks pretty cool, too. :)
