[30 second exposure shows visible light given off from unpeeled tape]
Read it here!!
We all love scotch tape. It's semi-invisible, it wraps our gifts, and we can stick it to our faces when we get bored.
However, that roll of scotch tape can actually produce x-rays. In a vacuum. (That means you cannot sit there and try to make x-rays at your desk at work.)
The physical peeling of the tape releases electrons which in turn, "generated strong, short bursts of X-rays — each burst, about a billionth of a second long, contained about 300,000 X-ray photons." The analogy they use is a "microscopic lightening effect."
Apparently, the Scotch-tape-is-AWESOME concept is nothing new. Russian scientists had stated that there were strong enough currents for x-rays back in 1953, but no one believed them, because really, who trusts the Russians?
Like every discovery in science, this could lead to new technologies. And what I discovered from this article is that peeling tape gives off visible light because it is "an experiment anyone can conduct in a closet."
I know what I'm doing at work tomorrow.
[Sidenote: I know this goes against the rule by being about physics, but I mean scotch tape light!!]

Is there anything Scotch Tape can't do? No.
