Laser Viewing Tank

Designed by California Physics Teacher Dean Baird, this versatile system allows students to see and control light beams. Scattering agent added to water in the plastic tank make laser beams visible. Students easily control observations involving simple refraction and total internal reflection. Watch as physics teacher Robert Douglas discuss this great teaching tool. Students love laser demos, keep the excitement coming with this demo!

what is that for a substance he puts in there?

[Arborscientific]

If you are refering to the "Scattering Agent" that is added to the water in the tank, the kit comes with a solution for that purpose and allows the light beam to show up in the water while still keeping the water clear and transparent. If you want to try doing it yourself for an experiment, you could try using "PIne Sol" cleaning solution available from the grocery store.

omg its mr baird!!!

[sann24]

what if i wanna built a tank on my own for personal study? i am from pakistan n dont have these things easily available..please tell me wht can i use as scattering agent in such a case? thnk u

Thank you for the fast respond.

I am from Germany.

It is just pine Oil am i right?

No mixture of anything just that?

I am asking that Saft because i Need it immediately for a Students project :) !!!
