Here are two pieces of filter plastic you can see just plastic you can put them on top
of each other and you can see when you turn them
why does that happen?
um because there's microscopic lines on them You can't see them, what you see is just fingerprints
now the lines are both lined up, up and down so that's not going to do much
more blocking than it would on its own. But when you turn them it's a tight grid
which I can see through but it's really dark.
Now can you show the cool magic thing?
This is a piece of clear plastic with tape on it that's just scotch tape and packing
tape
turn one filter Woah!
Hold it up to the light. You can see it's changing colors
Wait slow down I'm not sure I got it
That is so crazy. Awesome. Thank you!
