    With a lens that big you could probably melt a hole to the core of the earth!

    If I'm understanding this correctly, the sun is hot. And when it's magnified it's real hot. I never would have thunk it!! :confused:

    Not all projection screens fresnel sense work the same. Mine is rather poor but the primary 3" lenses are great.

    Many an ant soul was liberated from is earthly casing in this manner when I was a lad growing up in Arizona. Sometimes I feel like I'm still working off the karma from those days. Unspeakable carnage...

    "With great power comes great responsibility"
    Keeping that in mind, I stay away from the big, TV sized lenses. The 8.5x11 lenses from the dollar store are big enough for fires and pennies. Those massive ones are scary powerful. I'd get in too much trouble. Bought a few more paper sized lenses just a few weeks ago.
    Do you think @dadman has forgiven me for destroying his penny?

    @jswi2374 I just googled the dollar store fresnels and a you tube popped up . I’m sure you noticed this but look
    at my pic above and notice all shade under neath the sheet except for the focal point . That would probably be a good way to judge the efficiency of a particular lens . If sunlight were leaking through less efficient .
