If lethal dose is a measurement based on MG/ KG, why do they need LD 50? Because you know a little bit of product with a high concentration of poison that can kill 50% of the population would take less than a large amount of product with a low amount of concentration of poison that can kill 50% of the population; however, both can kill 50% of the population.??? So why is some poison and the other is only caution?

with random number of candies its not possible to perform the test !! doesnt make any sense...

Hey Dutz: What about a hydraulic driven motor on the sprayer pump to maintain constant pressure, no matter what the engine rpm? What about a tractor foot throttle to adjust sprayer output on variable organic matter soil in a field? Also, what about using a foot throttle to adjust engine rpm to maintain same speed in going up a hill and then down a hill? I thought you honcho's had a college education.

im horny heheh

This was excellent. :)

i want more presentation sir

Excellent video. One question: on the area of influence model, aren't you building the end result into it (in the shape of the hole in the foam)? Wouldn't you rather no foam at all - just the wooden edges, to show how drawing water affects the water table?

So have you guys in Pennsylvania experienced any groundwater pollution from fracking yet?

Thank you for this video! Very good presentation.
