I have tried the water with milk

I can see the beam, but in water, the beam is only about 10cm.
Maybe I need a stronger laser.


Is 100mW strong enough? The beam has to be shown at least 70cm long.

Move this to your previous post so people know what you are talking about. Starting a new post like this just makes it confusing.

Oh.. Im sorry..

Tastier alternative to drinking water + milk.

Yeah... Don't start a new thread on the same topic. Really confusing.

What do you mean by the beam being 10cm?

So sorry T_T

I shooted(?) the laser to the water+milk liquid,
and the beam line under the water was only about 10cm..

I assume he is trying to see the beam of a laser, by making a translucent mixture of milk and water, and shining the laser into it. Like liquid fog I would imagine.

However, do to losses in the liquid, the beam only makes it 10cm into the water before not being visible anymore.

No such thing as too weak of a laser unless you are wanting it to burn...

That should work. How focused is your 100mw?

I dont have 100mw T_T
Actually, it is illegal to buy or sell lasers over 1mw in Korea..

So I am thinking of making one.
