Did you know you could use water to burn through wood or heat up a skillet? Sound kind of backwards, but watch this!
"This is a solar water lens that is almost 30 inches in diameter and
can burn through wood quickly. It delivers a very large powerful focal
point that is only useful around noon in the summertime when the sun is
directly overhead. The material is crystal clear vinyl shower curtain.
This lens concentrates about 500 watts of solar heat energy to a focal
point of 1 inch optimal with a 3-6 inch scatter."
This is the part where we say, "Don't try this at home." And if you do (like we just told you not to) don't bother claiming that we said you could... 'cause we didn't. Right here is where. ;)
