This is a recording of a recent live teleclass I did with thousands of kids from all over the world. I’ve included it here so you can participate and learn, too!
This class is all about Light Waves, Lasers and Holograms! This is a newly updated version of the older Light Waves and Lasers teleclass here.
We’re going to learn about the wild world of light that has baffled scientists for over a century. You’ll be twisting and bending light as we learn about refraction, reflection, absorption, and transmission using lenses, lasers, mirrors, and optical filters with everyday stuff like gummy bears, paperclips, pencils and water!
We’re going to learn how to build a projection hologram out of piece of old plastic, make a laser microscope so you can see tiny little microscopic creatures, bend laser light to follow any path you want without using mirrors, and finally understand how glow in the dark toys really work on the subatomic level. Are you ready?

The video doesn’t work. How are we able to watch them Please?
Yes, any red laser will work! Here’s the ones I use when I teach a class of kids:

Hi there! I’m trying to prepare the materials for our first day of science class…what exactly is a “red laser”…what item do I look for online? Can you suggest a link from Amazon.com for a red laser which would work in this lesson project? Thank you!
No, wait, it works! Hope to learn more and more from your fantastic videos!
The video won’t work, and I already checked the internet 🙁 I love your videos and would love to watch it!
This amazed my whole family! SO COOL! Thank you so ya’ll! <3
