Hi,
in school, we talked about Quantum tunnelling. The teacher mentioned there is an experiment, pointing a high-powered laser (he said the laser used when he watched the experiment had about 250mW) on a piece of carton. Normally, the laser would not be able to shine through the piece of carton but in the dark you should be able to see photons that tunnled through it.
My teacher was not allowed to show this experiment since high powered lasers are allowed for personal use in Germany only, otherwise you have to own a certificate. He did not want me to do the experiment on my own, it would be "too dangerous" to use high powered lasers.
I am very interested in this experiment, does anybody know how to perform this experiment? Does anybody know similar experiments (especially experiments dealing with quantum physics)?
Thanks
Gabriel
