Super Fun!
Kia ora, I've purchased a few packets of the diffraction glasses now, as I keep giving them away to the kids! These glasses are a personal favourite of mine. I am a Science Communicator, and the glasses are a great and easy way to begin a conversation about light and wavelengths, and they impress people young and old.
I have just run an 'Edible Science' workshop, where I used large diffraction grating sheets to make Diffraction Chocolate, and then gave the kids a pair of diffraction glasses each to explore more about the make up of light, before going on to use UV lights and glow in the dark jello to talk about different wavelengths of light.
I recommend these glasses for science, and for fun!!
