That is what I was thinking. When I was teaching physical science for eighth graders, I got yelled at for sipping on water in the so called "lab," which consisted of a lab bench with no chemicals or biologicals, no hood, just a sink and water faucet. I did demonstrations of pulleys, density, and other non-harmful demos. Frank
Can you test some water before and after using a Berkey water filtration system? Maybe using some pond water.? And submit a video of this with before and after analysis. Thanks.
Way better than my teacher's explanation. Thank you!
No eating or drinking in the lab.

Firing a lighter is also not recommended... But nice explanation!
Excellent Video, looking forward to the next "Lab Report"
@PerkinElmer Could you update the link in the description?
Nice for improving knowledge

I have an ELAN9000 ICP/MS and it cranks the samples out, drinking water leads are faster than bacti's!
Field preserved? Or with preservation, +16 hours before checking turbidity, and maybe digestion?
@@one_hoop Gezus that was 3 yrs ago, that ICPMS has since died and replaced....field preserved and if turb is low enough dont have to digest.
Nice and informative for students. N.B., Only experts are allowed to drink or maybe to eat in the laboratories. Thank you, Paul, just kidding.
Is this technique for metals identification only ?
it can identify a few non-metals but i think is mostly used for metals
A bit late, but 200.7 includes minerals as well.
nice
