Heisenberg Uncertainty Principle Party Trick

You'll either be the hit of the party or you will clear the room. No uncertainty about that!

Wonderful but sad : I'm sure that I'll have to find a new party !…

Thank you for your contributions! I always enjoy seeing a new project from you.

There are more dazzling things to do with a laser. But this was interesting.

I should point out that photons taking the Alpha Centuri route from the razor blades to the target would take about 8 years, the lunar trip only about 4 seconds.

Would it be possible that the laser light is actually reflecting off the razors' edges causing it to deflect sideways? Even though the razor is sharp, there is an edge for the light to reflect off, though slight.

You are correct. It is a classic diffraction pattern caused by the edges of the razorblades that nevertheless behaves in accordance with the Heidelberg Uncertainty Principle.
