Pretty sure any red or green laser pointer will work. Clear colloidal silver is nano size - tiniest of particles. After a few days if it turns yellow, some silver has clumped together. I think I read somewhere that the yellow tone is the silver particles reflecting the light. So the larger the particles or the most concentrated will have a color tone. But nano size the silver particles are so tiny, it does not have a yellow tone. But the laser can pick it up.

Question was:
"How to use the laser pen to check if my colloidal silver is turning into colloidal silver....."?
How do we know if the clear solution is actually a colloidal silver solution?
Following the Spooky2 instructions/settings in calculator for producing 1000ml of liquid colloidal silver (25 hours) I never achieved .2 mAmp, water was always clear.
At times during the batches I found particles in motion with both white flashlight and spooky2 Red laser , mAmps varied from .04 ~ .17 , averaging around .09 mAmp.
Ran 4 batches with same distilled water batch with similar observations, Sometime during the the last 4-6 hours of Batch#4 the Spooky2 Magnetic Stirrer (SN: 162841, purchased Jan 17 2018, Invoice # 100020120) failed, completely dead, power/transformer was still warm, stirrer cold. Several un-plug/re-plug failed to bring the stirrer to life. power source working normally, tested other devices.
HELP!
Cordially,
William L Clark
My magnetic stirrer stopped work too!
