This is an old flash video that I think originated from newgrounds. The first 28 seconds or so is just an intro, so if you are impatient just skip ahead…
I found this on reddit a few days ago, I don't know the original source but I think it's a very good little illustration. (Appropriately enough, it involves lobsters as well
)

(an instructional guide, step 1 is the most important)

Some more oldschool internets:
"Magnet’s made of iron, lobster made of meat!" 
So does these guyz
