Maybe you could cote them with something that tastes really bad to the fish
so that they just spit them out???

I thought it was the other way around ... warmer water is less dense...

store that sells them and ask to see a "charger"... Read the label on the
transformer (volts and amps) and ask it the charger has any circuits in it
to prevent over charging... also ask how long it take to fully charge...
You may glean all you need to know...

cruise missile just flies over you head and keeps going...
But what you did not see was that it was ejecting small packages along the
way ... suddenly men start falling by the hundreds as insect size bots
inject them through their cloths... Is it a mosquito??? A cockroach??? or
could it be a specialized robot sent to seek you out ... ???... what defence
do you have against a billion little eyes???

I think it should be the other way around wrt temperature. Density of
water increases with falling temperature until it reaches 4 degrees
Centigrade. At this point the water is densest. Below 4 degree C, the
density decreases again. So the bot should become more buoyant with
increase in temperature if you disregard the little zone between 0 to 4
degree C.

No, I don't think so. You can't honestly believe that genetic material
makes one act a certain way. You are taught whether intentionally or
unintentionally whatever it is that make you you, throughout your lifetime.
Modern American psychology upholds this belief. Now I can understand that
maybe someone who reacts to stress with say an ulcer, may have children who
react in the same way....but when it really comes down to it, a violent
person TEACHES his/her children to react violently...it isn't just passed on
through genetics. Twin studies have proven this to be more than often true.
Sorry...don't mean to get my feathers ruffled up....I just can't fathom that
my personality was passed on from my parents by any means other than good
old fashioned authoritative teaching.
