Join the science discord!   / discord   Hey everybody! Ive wanted to make one of these forever. Well, i have made one before but it was not a 'good' fresnel lens. If you want to learn more about fresnel lenses this is a good website - https://rimstar.org/equip/fresnel_len... They have a youtube channel too with lots of educational content.    / rimstarorg
