Need Laser Experiment Suggestions

I am a little new to lasers. I used to have fun with my $2 red keychain laser but I WANTED MORE POWER :rock:sooo

I just bought a 50MW green laser and can't wait till it arrives. I live in NZ. I know the safety hazards and laws etc. But was wondering what cool -safe- experiments to try with it. Of course im gna try as much things as i can neways. But wanted to know if any1 had any awesome ideas?plz plz plz

Try pointing it into your bugger. Maybe the laser beam will shoot through your colon and shine out of your {term for male urinator/inseminator}!

I am not going to gain any fans for saying this, I am sure. But, That was one funny reply.

Trolls can be funny.

Aw, come on man. The term was a euphamism for a birds beak. :naughty:

Get one of those Radiometers (the little 4-vane thingee on a needle spindle inside an evacuated globe - looks like a big light bulb) - it's amazing how fast a multimilliwatt laser will turn that thing.

Get some microscope slides and experiment with beam splitting. Angle the slides and see how the beam splits off.

Investigate the refractive index of different fluids. Water, vodka, salt and sugar water, etc.

Get a few cheap lenses and experiment with beam expansion, collimation, and interference patterns (shine the expanded beam through a tiny aperture or slot).

Above all be careful to avoid reflections back into your eyes - or other bodily openings

Try putting a drop of water on a piece of glass and shining the laser through it from the bottom, It acts like a microscope, you can see the image on the roof. It looks better with dirty water.

Make a time tunnel effect with by attatching a small round mirror tilted at an angle to a small battery powered motor. Turn it on and shine the laser into it to make a cone shaped tunnel but be careful and wear goggles.
