>all the brainlets in this thread

You can do it with one use of the scale. Put all the pills on then remove them one at a time. When the weight drop changes, you got your poison pill.

If you put 2 on each side

If it is equal then 4 pill are not poisonous
The other 4, two out of four should be equal. 6out of 8 you can eat.

If you take four and 2 ISIS heavy then. The heavy wine is the poison is 1 out of 8. So 7 would allow anyone to let people eat their 7 out of 8.

So 1 ir 2 is poisonous.
Which means anyone can avoid the poisonous onep

How else do you get the pills off the scale without swatting them onto the floor and spilling them?
