my children go to school, but then I like to teach some little things as well, tricks and physics that will serve them down the line if they need to improvise. I got the little mirror to show them that they can start a fire with glass and no lighter, they absolutely loved it, plus I don’t have to feel bad that they’re outside magnifying ants to death because the way this lens is shaped that simply would not work. Well-made, reflection mirror, do not shine into eyes.
