Inspired by the thread on how many m&m’s or other would fit in a jar…
A friend of mine wants to collect a million pennies for charity. She suggested that people save them, put them in milk jugs, and she’ll load them into the back of her truck to take to the charity.
How much would they weigh? I’ll put my calculations in spoiler.
[spoiler]Per Wikipedia, one penny weighs 2.50 grams. Wheat pennies were 3.11 grams, but they’re rare. So if we had a million, that would be 2.5 million grams.
I could divide by 454g/lb, but I used the Yahoo conversion calculator, since it might have a very precise equivalent. 2.5 million grams is equivalent to 5511.55655462 pounds. Imagine if they were all wheat pennies!
2.75 tons means your average F150 isn’t going to cut it—multiple trips are required.[/spoiler]
She googled and found
2L Soda Bottle=4363 or $43.63
Milk Jug (1 Gal.)= 6,000 or $60.00
Water Jug (5 Gal.)= 70,000 or $700
It’s interesting that in the thread that inspired this, they’re talking about “packing efficiency” as well. I.e. how much space is “wasted”—just air? For the milk jug especially, I’m not sure I can calculate that to corroborate. For one thing, part of the gallon is the handle…would pennies fit in there? If so, how much “wasted” space?
That aside, a stats prof in college said that pennies aren’t fair coins. He said that if magnified, their shape would reveal itself not to be truly cylindrical, that it’s shaped more like a bottle cap. Tossing the coin over and over and letting it land on a level floor, you’ll get more heads than tails.
IMO the milk jugs are a bad idea. The weight of 6000 pennies is much more
I calculate it’s just over 33 lbs
than the jug was designed to hold. If she hit a bump in the road, she might have 6000 pennies x number of broken jugs all over the bed of her truck.
I think 2 liter soda bottles would be the best. They’re designed to keep the soda carbonated, so they’re sturdier, thicker plastic. Notice I said “soda bottles” because there may be those designed for water etc. may not be designed to the same specs.
A dramatic demonstration of their strength: the dry ice bomb. Everybody and his brother in here has seen this, right? Kids (and the moronic at heart) go out and buy some dry ice. They put some water in a 2 liter bottle—maybe about 1/4 full. Then they add pellets of dry ice, screw the top on and get back.
Mild but possibly NSFW…expletives in the “soundtrack.”

Look at how the plastic deforms at the top right before the explosion…man, that is insane!
Oh, and she better have bungee cords so that they can’t roll around in the bed, creating impacts like bowling balls.
Does my math check? What would you use to transport them? As disposable stuff goes, I think the 2L bottle is probably a pretty good piece of engineering, but maybe there’s something better.
