Try at home: Opening some envelopes (or similar) fast produces a blue light.
Wow, is that cerenkov radiation?
Doubtful. Probably static electricity.
Probably. My flatmate was still impressed, when I showed him.
This is about a year old, so what has happened in the meantime?
The scientists have been trying to get that #¤%& tape off their hands, so they can keep working.
Is this dangerous for people using a lot of stick tape?
"The pulses last for a billionth of a second, with an intensity of 100 milliwatts."
And this was in a vacuum "to reduce the interference of gas particles".
So I guess not.
Thanks. Still I wonder how it was possible to xray a finger using (if I guess correctly form what's written in the article) a single sticky tape without it emitting enough radiations to be dangerous for people unrolling a lot of sticky tape for work, with similar speed of 3 cm/s (this is more or less the "natural" unrolling speed when you are packing something requiring large strips).
