So, here I am again, and I have now built a strong laser which can set things on fire. Yay me. :D
But, the second step comes in..how am I supposed to expand the laser beam? The beam is a 0.2 cm circle, and I need to get it to at least 2.5 cm. Can somebody explain how I can do this? (Try not to bring water unless it's neccesary)
Thank you to anybody who answers. :D
